摘要：

The copolymers of poly [HEMA-co-(PVA-AA)] and poly[HEMA-co-(PVA-MA)] were synthesized and characterized. The presence of PVA-AA in the copolymer increased the mechanical strength but decreased the water content of the material. The presence of PVA-MA, on the other hand, caused a decrease of mechanical strength and an increase of water content. The ionization of acidic group in poly [HEMA-co-(PVA-MA)] resulted in the swelling of the copolymer, and the swelling extent was controlled by the change of pH. Both copolymers have great potential in biomedical application.
