ORGANOLITHIUM POLYMERIZATION INITIATORS AND USE THEREOF IN POLYMERIZATION PROCESSES

摘要

Polymerization initiator compositions comprising reaction products of C2-C12 alkyllithiums with monomers from the group of polymerizable conjugated dienes and polymerizable vinyl-substituted aromatic compounds in a medium of aliphatic, cycloaliphatic or aromatic hydrocarbons and/or aliphatic tertiary monoamines or aryl ethers, the conjugated diene and vinyl-substituted aromatic compound portion of said initiator compositions being relatively nonpolymeric. Such initiator compositions are highly effective for the productions of polymers of conjugated dienes and/or vinyl-substituted aromatic compounds.
