PROCESSES FOR IMPROVING STABILITY OF LIVING POLYMERIZATION CHAIN ENDS

摘要

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.
