摘要： This invention is based upon the unexpected discovery that alkylated diphenylamines can be used in conjunction with nickel based catalyst systems which contain (a) an organonickel compound, (b) an organoaluminum compound, and (c) a fluorine containing compound to produce cis-1,4-polybutadiene having reduced molecular weight and an increased level of branching. This results in the cis-1,4-polybutadiene exhibiting good processability without sacrificing cold flow characteristics. Additionally, the alkylated diphenylamine which remains in the rubber acts in a manner which provides it with antioxidant protection. In other words, the use of alkylated diphenylamines accomplishes the three major objectives that are realized by employing para-styrenated diphenylamines (reduced molecular weight, regulated polymer macrostructure through branching and antidegradant protection). However, the utilization of alkylated diphenylamines, unlike para-styrenated diphenylamines, offers the additional advantage of being soluble in aliphatic solvents. By virtue of this increased level of solubility in aliphatic solvents, such as hexane, alkylated diphenylamines can be employed at greatly reduced levels of aromatic solvents. Likewise, when mixed catalyst streams containing alkylated diphenyl amines are combined precipitation is minimized compared to para-styrenated diphenylamine significantly improving issues related to fouling. The subject invention more specifically discloses a process for producing cis-1,4-polybutadiene having a reduced molecular weight and improved processability which comprises polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound, and (d) an alkylated diphenylamine; wherein the alkylated diphenylamine has alkyl groups that contain from 2 to 18 carbon atoms, and wherein the organoaluminum compound and the fluorine containing compound are brought together in the presence of the alkylated diphenylamine.

摘要： The invention provides a process for commercial production of syndiotactic polyolefins using a metallocene catalyst supported on silica treated with MAO. The invention includes contacting the supported metallocene catalyst with an aluminum alkyl and aging the catalyst prior to polymerization. In addition, the catalyst is prepolymerized in a tubular reactor prior to being introduced into the polymerization reaction zone. The treated silica is produced by removing water to a level of 0.5-1.08%, slurrying in a nonpolar solvent, adding an alumoxane, heating to reflux, cooling the slurry, and separating the solid product.

摘要： High melt flow olefin polymers suitable for such applications as injection molding, and the like requiring a narrow molecular weight distribution are produced using a catalyst made by reducing and reoxidizing a chromium catalyst on either a titanium-silica cogel or a self-reduced silica-containing composition. In the first embodiment, a cogel formed by coprecipitating silica and titania, and containing a chromium compound, is treated in a nonoxidizing atmosphere, such as CO, hydrogen, N.sub.2 or a material decomposable to these materials, and thereafter reoxidized. In the second embodiment, a titanium-free chromium containing catalyst is first heated in air or the like to dry the catalyst and oxidize the chromium after which it is heated in an inert atmosphere wherein the composition is self-reduced to give chromium in a lower valence state. The resulting self-reduced composition is then heated in a reducing ambient and then reoxidized as in the first embodiment.
