Abstract

Cellulose esters of cinnamic acid, vinyl acetic acid, and fumaric acid monoethyl ester with moderate degrees of substitution were copolymerized with styrene, butyl methacrylate, and acrylic acid, respectively. Although high grafting ratios were obtained, crosslinked systems were formed despite attempts to manipulate pendant group reactivity vs. that of the grafting comonomer or the polymerization time and temperature. However, addition of a simple thiol chain-transfer agent resulted in soluble, noncrosslinked graft copolymers with moderate conversion (>40%) and grafting ratios to 170%. Structural elucidation of the graft copolymers was accomplished by FTIR and NMR spectroscopy. (C) 1997 John Wiley & Sons, Inc.
