Abstract
The invention describes the preparation and use of cellulose esters grafted with silicon-containing thiol pendent groups which can serve as crosslinking agents during free radical polymerization of ethylenically unsaturated materials. The grafted cellulose esters provide a crosslinked polymeric network with enhanced solvent resistance and hardness properties when used in conjunction with ethylenically unsaturated materials.
