Poly(vinylphosphonate)s with Widely Tuneable LCST: A Promising Alternative to Conventional Thermoresponsive Polymers
关键字：Group transfer polymerization, cloud point, poly(vinylphosphonate)s, rare earth metals
Novel statistic copolymers of dialkyl vinylphosphonates have been synthesizedvia rare earth metal-mediated group transfer polymerization using easily accessible tris(cyclopentadienyl) ytterbium. The copolymerization parameters have been determined by activity measurements showing the formation of almost perfectly random copolymers (r1, r2 ~ 1). Thus, the polymerization rate of vinylphosphonate GTP...
