Abstract
A method for preparing a functionalized polymer, the method comprising the steps of (i) polymerizing monomer with a coordination catalyst to form a reactive polymer; and (ii) reacting the reactive polymer with a carboxylic or thiocarboxylic ester containing a silylated amino group.
Claims38
A method for preparing a functionalized cis-1,4-polydiene polymer, the method comprising the steps of:
- (i) polymerizing conjugated diene monomer with a coordination catalyst to form a reactive polymer having a cis-1,4-linkage content that is greater than 60%;
- and
- (ii) reacting the reactive polymer with a carboxylic or thiocarboxylic ester containing a silylated amino group.
