An anionic polymerization initiator comprising the reaction product of a functionalizing agent selected from the group consisting of substituted aldimines, ketimines and secondary amines and, an organolithium compound. Elastomeric polymers prepared with these initiators have functional sites incorporated at the initiator end of the polymer chain and provide vulcanizable rubber compounds exhibiting reduced hysteresis. Articles such as tires, produced with low hysteresis elastomeric polymers have lower rolling resistance. Methods are also provided for preparing the initiators, functionalized polymers and vulcanizable elastomeric compounds having reduced hysteresis.
一种阴离子聚合引发剂,包括从取代醛亚胺、酮亚胺和仲胺组成的组中选出的官能化剂与有机锂化合物的反应产物。使用这些引发剂制备的弹性聚合物在聚合物链的引发剂端具有官能团,可提供硫化橡胶化合物,减少滞后现象。使用低滞后弹性聚合物生产的物品(如轮胎)具有较低的滚动阻力。此外,还提供了用于制备引发剂、官能化聚合物和可硫化弹性体化合物的方法,这些引发剂、官能化聚合物和可硫化弹性体化合物具有较低的滞后性。
