摘要： LA PRESENTE INVENCION SE REFIERE A LOS BENEFICIOS VARIOS QUE PUEDEN LOGRARSE MEDIANTE LA UTILIZACION DE TRANS - 1,4 POLIBUTADIENO EN COMPUESTOS CAUCHOTOSOS DE NEUMATICOS. POR EJEMPLO, LA RESISTENCIA EN BRUTO DE DICHOS COMPUESTOS CAUCHOTOSOS PUEDE MEJORARSE MEDIANTE LA INCLUSION DE TRANS - 1,4 - POLIBUTADIENO EN LOS MISMOS. DICHA INCLUSION TAMBIEN ES BENEFICIOSA DEBIDO A QUE DICHO COMPUESTO TRANS - 1,4 - POLIBUTADIENO ES CRISTALIZABLE POR DEFORMACION, SIN EMBARGO, DEBIDO A SU ELEVADO PUNTO DE FUSION, ES NORMALMENTE NECESARIO CALENTARLO PARA QUE ESTE PUEDA SER PROCESADO UTILIZANDO EQUIPAMIENTO DE MEZCLA CONVENCIONAL. DICHA ETAPA DE CALENTAMIENTO SE LLEVA A CABO MEDIANTE EL ALMACENAMIENTO DE DICHO TRANS - 1,4 -POLIBUTADIENO EN UNA CAMARA DE CALEFACCION DURANTE UNOS POCOS DIAS PREVIOS A SU UTILIZACION. DURANTE DICHO PERIODO DE ALMACENAMIENTO, DICHO POLIMERO EXPERIMENTA TIPICAMENTE UNA RETICULACION OXIDATIVA INDESEABLE, CAUSADA POR LA PRESENCIA DE CATALIZADOR DE COBALTO RESIDUAL, LO CUAL CONDUCEA LA GELIFICACION. DE HECHO, ESTA GELIFICACION PUEDE CONVERTIR A DICHO TRANS - 1,4 - POLIBUTADIENO EN IMPROCESABLE. ESTA INVENCION SE BASA EN EL HALLAZGO INESPERADO DE QUE DETERMINADOS ACIDOS BENZOICOS SUSTITUIDOS, TALES COMO ACIDO SALICILICO, ACIDO TIOSALICILICO Y ACIDO ACETILSALICILICO, ACTUAN COMO DESACTIVADORES METALICOS EN POLIMEROS. MEDIANTE LA UTILIZACION DE LA TECNICA DE LA PRESENTE INVENCION, EL COBALTO Y/O OTROS METALES RESIDUALES, COMO EL NIQUEL, QUE ACTUAN COMO PROOXIDANTES EN POLIMEROS, TAL COMO DICHO TRANS - 1,4 - POLIBUTADIENO, PUEDEN SER DESACTIVADOS. LA PRESENTE INVENCION DESCRIBE ESPECIFICAMENTE UNA COMPOSICION DE DICHO TRANS - 1,4 - POLIBUTADIENO ESTABILIZADA QUE INCLUYE DICHO TRANS - 1, 4 - POLIBUTADIENO Y UN ACIDO BENZOICO SUSTITUIDO SELECCIONADO A PARTIR DEL GRUPO FORMADO POR ACIDO SALICILICO, ACIDO TIOSALICILICO Y ACIDO ACETILSALICILICO

摘要： This invention is based upon the unexpected discovery that elastomeric trans-1,4-polybutadiene can be made by utilizing a catalyst system that is comprised of an organocobalt compound, an organoaluminum compound, a para-alkyl substituted phenol, and ortho-phenyl phenol wherein the molar ratio of the para-substituted phenol to the organoaluminum compound is within the range of about 1.2:1 to about 1.8:1, and wherein the molar ratio of the ortho-phenyl phenol to the organoaluminum compound is within the range of about 0.7:1 to about 1.3:1. Accordingly, the elastomeric trans-1,4-polybutadiene made by the process of this invention does not need to be heated, such as in a hot-house, before being used in making rubber stocks.

摘要： By utilizing the vapor phase polymerization techniques of the present invention, numerous distinct and highly beneficial advantages are realized. For instance, cis-1,4-polyisoprene rubber and high cis-1,4-polybutadiene rubber having a consistent and controllable molecular weight can be easily and practically prepared without utilizing a solvent. The subject invention more specifically discloses a method for vapor phase polymerizing isoprene into cis-1,4-polyisoprene in a process comprising the steps of: (1) charging into a reaction zone said isoprene and a preformed catalyst system which is made by reacting an organoaluminum compound with titanium tetrachloride, preferably in the presence of at least one ether; wherein the isoprene is maintained in the vapor phase in said reaction zone by a suitable combination of temperature and pressure; (2) allowing said isoprene to polymerize into cis-1,4-polyisoprene at a temperature within the range of about 35 DEG C. to about 70 DEG C.; and (3) withdrawing said cis-1,4-polyisoprene from said reaction zone. It has been determined that gel formation can be reduced by conducting the polymerization of isoprene monomer in the presence of a diarylamine, such as para-styrenated diphenylamine.

摘要： Certain substituted benzoic acids, e.g. (thio)salicylic acid, acetylsalicylic acid can be used as deactivators in cobalt-based catalytic systems used in the synthesis of syndiotactic 1,2-polybutadienes in aqueous solution. A stabilized syndiotactic 1,2-polybutadiene (SPBD) composition contains syndiotactic 1,2-polybutadiene and a substituted benzoic acid of formula (I). R = -OH, -S(=)OH, or -OC-R ; R = 1-12C alkyl; and R -R = H or 1-12C alkyl. An Independent claim is included for the preparation and deactivation of syndiotactic 1,2-polybutadiene involving (1) polymerization, e.g. suspension polymerization, of 1,3-butadiene in aqueous medium in the presence of a catalyst system, which includes (a) a transition metal compound, (b) an organoaluminum compound, and (c) at least one member from the group CS2, phenylisothiocyanate and xanthogenic acid, in order to obtain an aqueous medium containing 1,2-polybutadiene; and (2) addition of a substituted benzoic acid to the aqueous medium in order to deactivate the catalyst.

摘要： Various benefits can be attained by utilizing trans-1,4-polybutadiene in tire rubber compounds. For instance, the green strength of tire rubber compounds can be improved by including trans-1,4-polybutadiene therein. The inclusion of trans-1,4-polybutadiene in tire rubber compounds is also beneficial because it is strain crystallizable. However, due to its high melting point, it is normally necessary to heat trans-1,4-polybutadiene in order for it to be processed using conventional mixing equipment. This heating step is typically carried out by storing the trans-1,4-polybutadiene in a "hothouse" for a few days prior to its usage. During this storage period, the polymer typically undergoes undesirable oxidative crosslinking which is caused by residual cobalt catalyst and leads to gelation. In fact, the gelation can render the trans-1,4-polybutadiene unprocessable. This invention is based upon the unexpected finding that certain substituted benzoic acids, such as salicylic acid, thiosalicylic acid and acetylsalicylic acid, will act as metal deactivators in polymers. By utilizing the technique of this invention, residual cobalt and/or other metals, such as nickel, that act as prooxidants in polymers, such as trans-1,4-polybutadiene, can be deactivated. This invention more specifically discloses a stabilized trans-1,4-polybutadiene composition which is comprised of trans-1,4-polybutadiene and a substituted benzoic acid selected from the group consisting of salicylic acid, thiosalicylic acid and acetylsalicylic acid.

摘要： High vinyl polybutadiene rubber is utilized in a variety of applications. For instance, high vinyl polybutadiene is utilized in tire tread rubber compositions because it provides both good traction and rolling resistance. The present invention discloses a technique for synthesizing high vinyl polybutadiene utilizing a molybdenum catalyst system. This molybdenum catalyst system can be utilized in aliphatic solvents with high yields of about 75% being attained. The molybdenum catalyst systems of this invention are comprised of (a) a molybdenum containing compound which is prepared by modifying molybdenum pentachloride, molybdenum trichloride, or molybdenum tetrachloride with an alkyl carboxylic acid or an aryl carboxylic; and (b) an aluminum containing compound which is prepared by modifying a trialkyl aluminum compound with a phenol. The molecular weight of the high vinyl polybutadiene being prepared can be reduced by modifying the trialkyl aluminum compound with an allylphenol, such as 2-allylphenol.
