摘要: Polyester/polysiloxane copolymers are prepared by ring-opening synthesis of hydroxyalkyl- or aminoalkyl functional organopolysiloxanes from a cyclic silazane and an Si—OH functional polysiloxane, followed by reaction with a cyclic lactone such as a caprolactone. The process tolerates functional groups on the polysiloxane segments which are not possible in other synthetic methods.

摘要: Mono-hydroxyl-functional organopolysiloxanes are prepared with minimal byproducts and increased storage stability by reaction of cyclotrisiloxanes with sil(ox)anols containing less than 1 weight percent water in the presence of heterogenous alkali metal or alkaline earth metal oxide or carbonate catalysts.
摘要翻译: 通过在异源碱金属或碱土金属氧化物或碳酸盐催化剂的存在下,环状三硅氧烷与含有少于1重量%水的硅(ox)醇的反应,制备具有最小副产物和提高储存稳定性的单羟基官能的有机聚硅氧烷。
