✦ Synopsis


Bi-graft copolymers of poly(methyl methacrylate)-graft-[poly(ethylene oxide); poly(propylene oxide)] were synthesized by radical copolymerization of two macromonomers, viz. poly(ethylene oxide) methacrylate and poly(propylene oxide) methacrylate, with methyl methacrylate. The macromonomers were prepared by reaction of methacryloyl chloride with poly(ethylene oxide) and poly(propylene oxide) respectively. The copolymers were characterized by GPC, VPO, i.r. and ~H-NMR. Thermal and mechanical properties were examined and their properties were compared with monograft copolymers of poly(methyl methacrylate-g-ethylene oxide) and poly(methyl methacrylate-g-propylene oxide).
