INTERPENETRATING POLYMER NETWORKS OF PHOTOCROSSLINKABLE CELLULOSE DERIVATIVES

A series of interpenetrating polymer networks has been prepared from t wo cellulose derivatives, one of which contains cinnamate groups and t he other containing randomly substituted cinnamate and allyl groups. T he latter derivative forms a crosslinked network in less than 5 min on exposure to ultraviolet radiation and can be used to make amorphous i nterpenetrating polymer networks containing 50% by weight loading leve l of crosslinked vinyl polymers. The syntheses of both derivatives and the thermal properties and film morphologies of their interpenetratin g polymer networks are discussed. (C) 1996 John Wiley & Sons, Inc.
