Abstract

Recently, there was investigated the modification of hydrophilic polymers by graft copolymerization techniques to prepare products with good biocompatibility and biodegradability for hydrogels or highly water absorbent polymers. Poly(vinyl alcohol) (PVA) a highly hydrophilic polymer can be modified with vinyl monomers to obtain copolymers with improved properties. The study presents the synthesis of poly(vinyl alcohol)-acrylamide copolymers using as radical initiator benzoyl peroxide or as redox initiator potassium persulfate/ferrous sulfate, by solution polymerization procedure in water or ethylene glycol/water (1/3) mixture. The gravimetric ratio PAV/acrylamide was variable: 1/1; 1/2.33; 2.33/1. The obtained copolymers were characterized by infrared spectroscopy, elemental and thermal analyses, and swelling behaviour in distilled water..
