摘要：

Trimethylvinylsilane was found to polymerize anionically in cyclohexane much like styrene or dienes, except for the occurrence of a termination step. The propagation and initiation reactions were found to be first order with respect to trimethylvinylsilane and one-half order with respect to the initiator and chain ends initially, but first order after the initiator was consumed. Rate constants for initiation, propagation, and termination were found to increase in the presence of ethers, with the termination rate constant increasing the fastest. This study has implications for the synthesis of block copolymers.
