SYNTHESIS AND CHARACTERIZATION OF REACTIVE GRAFT COPOLYMER PDMS-g-(PEO-OH)*

Received Date: 31 January 1994

A new reactive graft copolymer, poly (dimethyl siloxane )-graft-ω-hydroxyl-poly(ethylene oxide) (PDMS-g-(PEO--OH)), was synthesized by the hydrosilylation reactionof α, ω-bifunctional PEO macromonomer (CH2=CH--CH2--PEO--OH) with poly(hydromethylsiloxane) (PHMS). The obtained copolymer, exhibited the expected comb-like structure as indicated by the result of detailed characterization and the neededreactivity as demonstrated by the result of esterification between PDMS-g-(PEO--OH)and aminoacetic acid. This reactive graft copolymer is expected to be very useful in the preparation of new bioactive polymer meterials.
