ABSTRACT:
A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a carbohydrate or protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer. By this process, a biodegradable interpolymer composition is produced that is suitable for molding various articles.
