以不同分量的α,ω-双(γ-氨丙基)聚二甲基硅氧烷预聚物为软段,分别以聚芳 酯、聚酰亚胺为硬段合成了嵌段长短不同及含量不同的聚有机硅氧烷-聚芳酯嵌段共聚物和聚有机硅氧烷-聚酰亚胺嵌段共聚物。以红外光谱、核磁共振方法测定了共聚物的结构及组成,使用透射电子显微镜、热机械曲线、示差扫描量热法及动态力学试验等研究了 Different lengths of α, ω-bis (γ-aminopropyl) polydimethylsiloxane prepolymer were used as soft segments and polyarylates and polyimides as hard segments, respectively. Polyorganosiloxane-polyarylate block copolymers and polyorganosiloxane-polyimide block copolymers differing in content. The structure and composition of the copolymers were determined by IR and NMR. The structures and compositions of the copolymers were studied by transmission electron microscopy, thermomechanical curve, differential scanning calorimetry and dynamic mechanical tests
