| Abstract: | In the terpolymerization of polyoxyethylene macromer, methyl methacrylate and butyl acrylate the polymerization rate and the effects of various factors on grafting efficiency and molecular weight of the terpolymers were studied. The terpolymers were purified by extractions and characterized by IR, NMR, DSC and membrane osmometry. The average grafting number was determined to be about 10. The terpolymers possess good emulsifying property, phase transfer catalytic ability and behave like a thermoplastic elastomer. |
