    摘要: The invention concerns a novel process for the preparation of poly(N-acylethyleneimine) grafted poysiloxanes comprising sulfoesterifying all or part of alcoholic hydroxyl groups of a hydroxy containing polysiloxane and conducting, in said sulfoesterification reaction mixture, ring-opening polymerization of a 2-oxazoline compound. The present process can afford the desired poly(N-acylethyleneimine) grafted polysiloxane in a higher reaction yield. The invention also provides novel poly(N-acylethyleneimine) grafted polysiloxanes.

    摘要: A process for preparing a polyester-modified silicone resin comprises mixing an alkoxysilane and/or its hydrolyzate, i.e. an alkoxysiloxane, and a polyester resin having at least two hydroxyl groups in the molecule, and subjecting the mixture to hydrolysis and polycondensation reactions in the presence of an acid catalyst. This process is performed by a continuous one-stage reaction sequence including hydrolysis, polycondensation and modification and is simplified. A composition comprising the polyester-modified silicone resin is also described. The composition comprising organozinc compounds along with the modified silicone resin is significantly improved in heat resistance and color-difference.
