TitleTITANIUM, ZIRCONIUM AND HAFNIUM ENOLATES ASINITIATORS IN THE POLYMERIZATION OF ACRYLICMONOMERS TO "LIVING" POLYMERSAbstractProcess for preparing "living" polymer, theprocess comprising contacting one or more acrylicmonomers under polymerizing conditions with apolymerization-initiating amount of a tetra-coordinate organotitanium, organozirconium or organo-hafnium enolate polymerization initiator, and"living" polymers produced thereby.
