PHOTOINDUCED POLYMERIZATION .4. GRAFT-COPOLYMERIZATION 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 polymerization of methyl methacrylate with quinoline derivatives and PEG. The separation of these graft copolymers from the simultaneously formed homopolymeric poly(methyl methacrylate) (PMMA) and the remainder of not converted PEO can be achieved by subsequent extraction with ethyl acetate and methanol. With that determination of graft yield, degree of grafting, grafting success, and grafting height are possible.
