摘要: This invention is a process for making difunctional lithium initiator which comprises reacting secondary or tertiary alkyl with diisopropenylbenzene compound in the presence of diethyl ether at temperature 25 to 50° C. wherein molar ratio from above 0.1:1 2:1 and are first mixed together then added alkyl. The should be as close 0.5:1 possible. An excess may used if product containing both diinitiator monoinitiator preferred. It preferred that 1:1
