Claims17
A process for preparing a functionalized anionic polymerization initiator, the process comprising:
- combining a functionalized styryl compound and an organolithium compound.
An anionic polymerization initiator defined according to the formula I:
- where each R1 is independently hydrogen or a hydrocarbyl group, R2 is hydrogen or a hydrocarbyl group, R3 is hydrogen or a hydrocarbyl group, each R4 is independently hydrogen or a monovalent organic group, R5 is a hydrocarbyl group, where at least one of R3 or R5 is hydrocarbyl, R6 is a covalent bond or a hydrocarbylene group, and A is a functional group.
A polymer prepared by a process of comprising the steps of
- polymerizing monomer with an initiator that is prepared by combining a functionalized styryl compound and an organolithium compound.
