Polymers functionalized with a carboxylic or thiocarboxylic ester containing a silylated amino group

摘要

A method for preparing a functionalized polymer, the method comprising the steps of: (i) polymerizing monomer with an anionic initiator to form a reactive polymer; and (ii) reacting the reactive polymer with a carboxylic or thiocarboxylic ester containing a silylated amino group, where the silylated amino group is directly attached to a moiety selected from the group consisting of acyclic moieties, heterocyclic moieties, and nonaromatic cyclic moieties.
