Capping reactions in cationic polymerization; kinetic and synthetic utility

摘要

A method of synthesizing an endcapped polymer, comprising reacting in a solvent a cationic living polymer with an optionally substituted conjugated diene as an endcapping reagent, whereby the solvent causes termination by halogenation to be faster than the addition of additional molecules of the conjugated diene, thereby producing an endcapped polymer having a halogenated endcap group.
