ABSTRACT:
An anionic polymerization initiator includes the C-lithio reaction product of an organolithium compound and a tertiary-amino allyllithium or a tertiary-amino xylyllithium. When used in an anionic polymerization, a functional group from the initiator is incorporated onto the head of the growing polymer and a lithium atom is incorporated at the "living" end of the polymer chain prior to quenching. The initiator may be used to polymerize a monomer(s) including diolefin monomers, monovinyl aromatic monomers and trienes, and the living ends of the polymers are effectively maintained even at temperatures of up to 300.degree. F. and higher. Such polymers exhibit an increased efficiency in coupling termination reactions, and products prepared from such polymers exhibit improved hysteresis characteristics. Products such as tires and the like can be prepared from such polymers and from vulcanizable elastomer compositions employing the polymers.
