PROCESS FOR PREPARING POLYMERS HAVING FUNCTIONAL GROUPS, POLYMER, POLYMERIC COMPOSITION, LITHIUM COMPOUND, AND PROCESS FOR PREPARATION THEREOF

摘要

FIELD: chemistry of polymers. SUBSTANCE: claimed invention describes polymerization of unsaturated monomers in the presence of initiators with functional groups having structure RRR-Si-O-A′-Li each of radicals R is methyl and A′ is -CH-CH-CH- or wherein -CHCR′R″-CH-, is linear alkyl containing 1 to 10 carbon atoms and R″ is hydrogen atom or linear alkyl containing 1 to 10 carbon atoms. This initiator renders the process and the product more advantageous as compared with prior art initiators of this type. EFFECT: improved properties of the polymeric composition.
