Titanium, zirconium and hafnium enolates as initiators in the polymerization of acrylic monomers to 'living' polymers

摘要

Process for preparing "living" polymer, the process comprising contacting one or more acrylic monomers under polymerizing conditions with a polymerization-initiating amount of a tetracoordinate organotitanium, organozirconium or organohafnium enolate polymerization initiator, and "living" polymers produced thereby.
