Protected functional initiators for making terminally functionalized polymers
摘要：
The anionic polymerization of unsaturated monomers with functionalized initiators having the structure R.sup.1 R.sup.2 R.sup.3 Si--O--A'--Li is improved when each R is methyl and A' is --CH.sub.2 --C.sub.6 H.sub.10 --CH.sub.2 -- or --CH.sub.2 --CR'R"--CH.sub.2 -- wherein R' is a linear alkyl having from 1 to 10 carbon atoms and R" is hydrogen or a linear alkyl having from 1 to 10 carbon atoms. This initiator provides process and product advantages over all other known initiators of the same type.
摘要（中）：

当R 1为甲基且A'为-CH 2 -C 6 H 10 -CH 2 - 或-CH 2 -CR'R“-CH 2 - （CH 3））时，不饱和单体与具有结构R1R2R3Si-O-A'-Li结构的官能化引发剂的阴离子聚合得到改善， 其中R'是具有1至10个碳原子的直链烷基，R“是氢或具有1至10个碳原子的直链烷基。 该起始物相对于相同类型的所有其它已知的引发剂提供了方法和产物优点。
