摘要： To provide a novel cross copolymer and resin composition which are improved in heat resistance and compatibility over conventional ethylene/aromatic vinyl compound copolymers and which have low crystallinity, are excellent in softness, transparency and compatibility and show mechanical properties similar to soft vinyl chloride resins, as compared with conventional cross copolymers.A process for producing a cross copolymer, which comprises a coordination polymerization step and a subsequent anionic polymerization step, wherein in the coordination polymerization step, copolymerization of an olefin monomer, an aromatic vinyl compound monomer and an aromatic polyene is carried out by using a single-site coordination polymerization catalyst to synthesize an olefin/aromatic vinyl compound/aromatic polyene copolymer, and then, in the anionic polymerization step, polymerization is carried out in the coexistence of such an olefin/aromatic vinyl compound/aromatic polyene copolymer and an anionic polymerizable vinyl compound monomer by using an anionic polymerization initiator.

摘要： This invention is based upon the discovery that the characteristics of toner resins made by emulsion polymerization can be improved by utilizing diacid cycloaliphatic emulsifiers in the synthesis thereof. Toner resins which are made utilizing such diacid cycloaliphatic emulsifiers do not exhibit significant electrical charge effects from the residual level of soap in the resin compared to resins made using standard soaps; such as, rosin acid soaps and fatty acid soaps. They also generally contain a lower level of ash since salts do not need to be used in their coagulation. As a result of the low level of ash, the toner resin made from the diacid soap exhibits excellent resistance to moisture sensitivity and adsorption. This feature gives the toners made from these resins better electrical charge stability compared to resins made from conventional soaps since adsorbed moisture is known to neutralize electrical charges. Toners made from these resins also exhibit greatly improved adhesion to paper. This invention more specifically discloses a process for preparing a polymer which is particularly useful as a toner resin, which comprises (1) emulsion copolymerizing a vinyl aromatic monomer and a second monomer selected from the group consisting of conjugated diene monomers and an acrylate monomer selected from the group consisting of alkyl acrylate monomers and methacrylate monomers in the presence of a diacid cycloaliphatic emulsifier to produce the polymer and (2) recovering the polymer from the aqueous emulsion.
摘要翻译：本发明基于以下发现：通过在其合成中利用二酸脂环族乳化剂可以改善通过乳液聚合制备的调色剂树脂的特性。使用这种二酸脂环族乳化剂制备的调色剂树脂与使用标准皂制备的树脂相比，不显示树脂中剩余残余水平的显着的电荷效应; 如松香酸皂和脂肪酸皂。它们通常还含有较低水平的灰分，因为不需要在其凝结中使用盐。作为灰分低的结果，由二酸皂制成的调色剂树脂具有优异的耐潮湿敏感性和吸附性。这种特征使得由这些树脂制成的调色剂与常规皂制成的树脂相比具有更好的电荷稳定性，因为已知吸附的水分中和电荷。由这些树脂制成的调色剂也显着改善了对纸的粘附性。本发明更具体地公开了一种制备聚合物的方法，其特别可用作调色剂树脂，其包括（1）将乙烯基芳族单体和选自共轭二烯单体和选自以下的丙烯酸酯单体的第二单体乳液共聚合：在二酸脂环族乳化剂存在下由丙烯酸烷基酯单体和甲基丙烯酸酯单体组成的组，以产生聚合物和（2）从水乳液中回收聚合物。

摘要： This invention provides a maleimide-based copolymer in which, because its molecular weight-retention ratio at high temperature is high, deterioration of physical properties by heating is little. Also, this invention provides a process wherein a maleimide-based copolymer is arranged so as not to heat more than necessity and thereby a maleimide-based copolymer containing only a small amount of residual volatile components is efficiently obtained without deterioration of physical properties. The maleimide-based copolymer is such as having a glass transition temperature of 170.degree. C. or higher, a weight-average molecular weight of 100,000 to 500,000, and a molecular weight-retention ratio of 90% or more when heated at 280.degree. C. for 10 minutes. When this copolymer is produced, volatile components are separated by supplying a polymer composition containing said copolymer and volatile components to a vent type screw extruder and operating this extruder under condition of a screw rotation number of 50 to 150 rpm.

摘要： Water-dilutable dispersions of acrylate copolymers having a hydroxyl number of from 40 to 200 mg KOH/g and an acid number of from 15 to 50 mg of KOH/g, obtained by free-radical copolymerization ofa) from 5 to 40 parts by weight of at least one glycidyl ester of an .alpha.-branched aliphatic saturated monocarboxylic acid,b) from 0 to 30 parts by weight of at least one diester of an .alpha.,.beta.-olefinically unsaturated dicarboxylic acid,c) from 0 to 70 parts by weight of at least one vinyl aromatic hydrocarbon, the molar quantity of component c) always being greater than or equal to the molar quantity of component b),d) from 0 to 60 parts by weight of an alkyl ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid,e) from 2 to 40 parts by weight of at least one .alpha.,.beta.-olefinically unsaturated carboxylic acid, the molar quantity of component e) always being greater than the molar quantity of component a),f) from 5 to 40 parts by weight of at least one hydroxyalkyl ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid,the polymerization being carried out in bulk or in solution; if desired, addition of a water-dilutable solvent, neutralization and dilution with water.These dispersions are suitable as water-dilutable binders for clearcoat baking enamels or solid-color topcoat baking enamels.
