ABSTRACT:
The invention concerns a novel process for the preparation of poly(N-acylethyleneimine) grafted polysiloxanes comprising sulfo-esterifying all or part of alcoholic hydroxyl groups of a hydroxy containing polysiloxane and conducting, in said sulfo-esterification 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.
