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

【摘要】 <正> 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 thepreparation of new bioactive polymer materials.更多还原
