ABSTRACT:
A nucleophilic displacement reaction is used to prepare biodegradable thermoplastic copolymers exhibiting a high capacity for stabilizing biodegradable blends of polysaccharides and synthetic thermoplastic polymers. The graft copolymers are characterized by consistent product uniformity and a high degree of substitution on the polysaccharide chain.
