Synthesis of graft copolymers from alpha-oxanorbornenyl macromonomers
alpha-Oxanorbornenyl macromonomers of poly(solketal methacrylate) were synthesized by ATRP with molar masses ranging from 3500 to 8500 g mol -1 and polydispersity indexes (PDi) of 1.22-1.23 prior to being polymerized via ROMP. Grubb’s second generation catalyst ((IMesH 2)(Cy3P)RuCl2(CHPh)) was employed to give complete conversion with PDi of approximately 1.25 obtained. Subsequent hydrolysis led to well-defined polyoxanorbornene-g-poly(glycerol methacrylate) copolymers via the “grafting through” strategy with number average molar mass of 24 000-37 000 g mol-1. A macromonomer with a molar mass of 6000 g mol-1 was the upper limit to obtain a complete conversion under the polymerization conditions employed.
