摘要：

Vinyl acetate was grafted on a block-copolymer of ethylene oxide with propylene oxide and on hydroxyethylcellulose. Films obtained from benzene solutions of these copolymers were studied by differential scanning calorimetry, gas chromatography and electron microscopy. The results revealed a two-phase morphology for both copolymers studied. After treatment at 60 degree C, the observed phase segregation disappeared only in the film prepared from the vinyl acetate grafted copolymer of ethylene oxide with propylene oxide.
