| 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.
