摘要
研究了一系列低分子量的α,ω-二羟基聚二甲基硅氧烷齐聚物及1,3-二(3-羟丙基)四甲基二硅氧烷的合成方法,制取了分子量可以控制的α,ω-二羟基聚二甲基硅氧烷低聚物。使之与聚氨酯预聚体进行共聚、形成一系列有机硅-聚氯酯嵌段共聚物。并对其反应动力学和共聚物的相态结构进行了研究。
The synthetic methods of low molecular weight α, ω-dihydroxy silozane oligomer (I) and 1,3-bis ( 3-hydroxyprophyl) tetramethyldissiloxane (II) were studied. A series poly (siloxane-urethane) block copolymers were prepared, from I, II with polyurethane prepoly-mer by co-condensation polymerization. Their reaction kinetics aad morphological structure were studied.
