Biodegradable copolymers. Part II. Properties of copolymers grafted onto gelatin

Polimery 1999, No 4, 241


DOI: dx.doi.org/10.14314/polimery.1999.241


Summary

Progress in studies on vinyl (mostly acrylic) polymers grafted onto gelatin and the physico-chemical and service properties of the copolymers are reviewed with particular reference to solubility, intrinsic viscosity, sorption of water, thermal stability, resistance to enzymatic attack, and mechanical properties of films. As the degree of grafting is increased, the resistance to bacterial enzymes rises. When the degree attains 200%, the copolymer is totally resistant to biodegradation. Possible applications of the copolymers are described.
Keywords: polymers grafted on gelatin, their physicochemical and service properties, biodegradability and applications
