  The present invention relates to a free radical emulsion polymerization process. The latex is prepared by polymerizing (a) at least one conjugated diene, (b) at least one non-carboxylic vinyl aromatic or aliphatic comonomer selected from the group consisting of styrene, α-methyl styrene, p-methyl styrene, vinyl toluene, acrylonitrile, methacrylonitrile, vinylidene chloride, ethyl acrylate, butyl acrylate, vinyl pyridine, methylmethacrylate, hexylacrylate, 2-ethyl hexyl acrylate or mixtures thereof, and (c) at least one ethylenically unsaturated carboxylic acid monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, 3-carboxyethylacrylate, itaconic acid or mixtures thereof. The process of the present invention is characterized by (a) initially polymerizing the non-carboxylic comonomer in the presence of the unsaturated carboxylic acid and in the absence of any conjugated diene to a conversion of 3 to 12 percent to form a partially polymerized latex; and thereafter (b) copolymerizing the conjugated diene with the unreacted non-carboxylic comonomer in the partially polymerized latex. The present process mitigates the formation of codimers of the conjugated diene and non-carboxylic comonomer. The present process also provides a latex having unique film forming characteristics and polymer morphology leading to unique film stiffness and stress-strain relationship.

  本发明涉及一种自由基乳液聚合工艺。胶乳是通过聚合 (a) 至少一种共轭二烯，(b) 至少一种非羧基乙烯基芳香族或脂肪族共聚单体而制备的，该共聚单体选自苯乙烯、α-甲基苯乙烯、对甲基苯乙烯、乙烯基甲苯、丙烯腈、甲基丙烯腈、亚乙烯基氯、丙烯酸乙酯、丙烯酸丁酯、乙烯基吡啶、甲基丙烯酸甲酯、丙烯酸己酯、丙烯酸 2-乙基己酯或它们的混合物、(c) 至少一种乙烯基不饱和羧酸单体，选自丙烯酸、甲基丙烯酸、马来酸、富马酸、3-羧乙基丙烯酸酯、衣康酸或其混合物组成的组。本发明工艺的特点是：(a) 非羧酸共聚单体在有不饱和羧酸和没有任何共轭二烯的情况下进行初始聚合，转化率为 3-12%，形成部分聚合胶乳；然后(b) 共轭二烯与未反应的非羧酸共聚单体在部分聚合胶乳中进行共聚。本工艺减少了共轭二烯和非羧酸共聚单体的形成。本工艺还提供了一种具有独特成膜特性和聚合物形态的胶乳，从而形成独特的薄膜刚度和应力应变关系。

  Polymeric reinforcements are commonly used to strengthen rubber articles. For instance, rubber articles are commonly reinforced with high strength cords, polymeric fabric and/or short fibers. It is often difficult to attain a high level of adhesion between such reinforcements and rubber compositions. This is especially true in cases where difficult to bond materials, such as polyaramide fibers, are employed. By utilizing the process of this invention, the adhesion between polymeric reinforcements and rubber compositions can be greatly improved. This invention more specifically discloses a process for preparing a rubber article containing a polymeric reinforcement which comprises: (1) plasma treating the polymeric reinforcement in a manner whereby reactive groups containing Zerewitinoff active hydrogen atoms are bonded to the surface thereof; (2) incorporating the polymeric reinforcement having Zerewitinoff active hydrogen atoms bonded to the surface thereof into an uncured rubber composition, wherein said rubber composition has pendant blocked isocyanate groups bound thereto; and (3) curing the uncured rubber into the desired shape for the rubber article at an elevated temperature sufficient to deblock the isocyanate groups bonded to the uncured rubber allowing for the isocyanate groups to react with the Zerewitinoff active hydrogen atoms bonded to the surface of the polymeric reinforcement.

  聚合物加固剂通常用于加固橡胶制品。例如，橡胶制品通常使用高强度绳索、聚合织物和/或短纤维进行加固。此类补强材料与橡胶成分之间通常难以达到高度粘合。在使用聚酰胺纤维等难以粘合的材料时，情况尤其如此。通过使用本发明的工艺，可大大提高聚合物增强剂与橡胶组合物之间的粘合力。本发明更具体地公开了一种制备含有聚合补强材料的橡胶制品的工艺，该工艺包括：(1) 等离子处理聚合物补强体，使其表面键合含有 Zerewitinoff 活性氢原子的反应基团；(2) 将表面键合有 Zerewitinoff 活性氢原子的聚合物补强体加入未硫化橡胶组合物中，其中所述橡胶组合物结合有悬臂封端异氰酸酯基团；(3) 在高温下将未固化橡胶固化成橡胶制品所需的形状，使其足以解除与未固化橡胶结合的异氰酸酯基团的阻塞，从而使异氰酸酯基团与聚合物补强体表面结合的 Zerewitinoff 活性氢原子发生反应。
