Polyester-polysiloxane block copolymers for dental uses are disclosed as low modulus thermoplastic elastomers. The copolymers comprise polycaprolactone residues and poly-(dimethylsiloxane) α. ω-diol residues which are linked by ether bonds. The compounds exhibit the property of plasticity by heating and the property of original rubber elasticity by cooling again to room temperature.
作为低模量热塑性弹性体,公开了牙科用聚酯-聚
硅氧烷嵌段共聚物。 共聚物由聚
己内酯残基和聚-(二甲基
硅氧烷)α.ω
-二醇残基组成,它们通过醚键连接。 这种化合物在加热时表现出可塑性,而在冷却至室温时又表现出原始橡胶弹性。
