摘要：
A copolymer having free hydroxyl groups is formed from N-vinyl pyrrolidone and allyl alcohol. A polyurethane is formed from a reaction mixture which includes the copolymer, a diisocyanate, a chain extender and a polyglycol. The polyurethane takes up iodine to give a complex useful as an antimicrobial coating on a medical article or as an antimicrobial foam sponge or wound dressing.
