PHOTOINDUCED POLYMERIZATION .4. GRAFT-COP OLYMERIZATION OF METHYL-METHACRYLATE ONTO POLY(ETHYLENE OXIDE) IN THE PRESENCE OF QUINOLINE DERIVATIVES

When using poly(ethylene oxide) (PEG) as a polymeric hydrogen donator, grafted polymerization products are obtained upon photoinduced polyme rization of methyl methacrylate with quinoline derivatives and PEG. Th e separation of these graft copolymers from the simultaneously formed homopolymeric poly(methyl methacrylate) (PMMA) and the remainder of no t converted PEO can be achieved by subsequent extraction with ethyl ac etate and methanol. With that determination of graft yield, degree of grafting, grafting success, and grafting height are possible.
