ABSTRACT:
Liquid telechelic polymers are made from dienes and are produced via anionic polymerization. While having low molecular weight, for example less than 15,000, the telechelic polymers are generally gel-free, have high amounts of trans-1,4 structure, low vinyl unsaturation and low bulk viscosities. The liquid telechelic polymers are made utilizing a trimetallic initiator comprised of (1) an organopolylithium compound and (2) a complex of a trialiphatic substituted aluminum compound or derivative thereof and a barium salt of an organic alcohol.
