摘要： It is highly desirable to be able to cure rubbers quickly since the amount of energy required for the curing process is reduced and the number of articles that can be cured in a mold in a given time is increased. In other words, the cycle time needed to cure articles made from such a rubber is reduced and the throughput of a mold utilized in curing such a rubber is increased. Unfortunately, most attempts to accelerate the cure rate of rubber have resulted in the rubber having poor scorch safety. The present invention discloses a fast curing rubber blend having excellent scorch safety which comprises: (a) from 50 to 98 weight percent of at least one polydiene rubber, and (b) from 2 to 50 weight percent of at least one vinylpyridine copolymer comprised of repeat units which are derived from a diene monomer and vinylpyridine wherein from 1 to 75 weight percent of the repeat units in said copolymer are derived from vinylpyridine. The rubber blends of the present invention have unexpectedly been shown to have particular utility in improving tire tread traction.
摘要翻译：由于固化过程所需的能量的量减少并且在给定时间内可以在模具中固化的制品的数量增加，所以非常希望能够快速地固化橡胶。换句话说，固化由这种橡胶制成的制品所需的循环时间减少，并且用于固化这种橡胶的模具的生产量增加。不幸的是，大多数加速橡胶固化速度的尝试导致橡胶具有差的焦烧安全性。本发明公开了一种具有优异的焦烧安全性的快速固化橡胶共混物，其包括：（a）50至98重量％的至少一种聚二烯橡胶，和（b）2至50重量％的至少一种乙烯基吡啶共聚物，衍生自二烯单体和乙烯基吡啶的重复单元，其中所述共聚物中1至75重量％的重复单元衍生自乙烯基吡啶。本发明的橡胶混合物意外地被证明在改善轮胎胎面牵引力方面具有特别的用途。

摘要： It is often desirable to utilize accelerators in the sulfur vulcanization of unsaturated rubbers. In many cases a primary accelerator is used in combination with another accelerator, called a secondary accelerator or activator, which further increases the rate of vulcanization. It has been determined that compounds having the structural formula:NH.sub.2 --A[NH--(CH.sub.2).sub.x NH].sub.n A--NH.sub.2wherein x is 2 or 3, wherein n is an integer from 1 to 100, and wherein A represents an alkylene group containing from 1 to 20 carbon atoms, act as secondary accelerators in the vulcanization of unsaturated rubbers. For example, it has been determined that 4,7-diaza-decane-1,10-diamine is a particularly desirable secondary accelerator.
