Termination of anionic polymerization

摘要

This is an improvement upon a process which comprises anionically polymerizing monomers with an anionic polymerization initiator in a suitable solvent thereby creating a living polymer. The improvement comprises terminating the polymerization by the addition of a terminating agent selected from the group consisting of hydrogen or its isotopes, boranes, ammonia, halogens, hydrocarbons containing a C-H group where the carbon is connected directly to a triply-bound carbon or to two doubly-bound carbons and silanes.
