Abstract (en)
[origin: WO9912979A1] Initiator compositions capable of imparting improved thermal stability of living polymerization chain ends and processes of using the same. The compositions include an alkyllithium initiator and a silyl ether. The silyl ether can be incorporated into the initiator (as a protected functionalized initiator), or as a separate small molecule added to the initiator solution.
