Procedure

A 6-ml flask was charged with 0.489 g of pyrithione methacrylate (2.5 mmole), 2.6 ml of styrene (22.5 mmole) and 0.083 g of AIBN (0.5 mmole). The flask was sealed and placed in an oven at 80° C. for 16 hours. After cooling to room temperature, the product was diluted with 10 ml of methylene chloride and filtered. The solution was concentrated via roto-evaporation and 1.66 g of the desired product was isolated as a yellow polymeric material for a 56.9% yield. The structure was confirmed by NMR and IR. Similar results were obtained by employing either acetyl peroxide, benzoyl peroxide, or lauryl peroxide as the radical initiator.
