Poly(2-hydroxyethyl methacrylate)-(PHEMA) has been prepared by polymerizing in presence of different types of water-soluble additives, at various amounts, which were removed by swelling in water. Mechanical properties of swollen samples have been measured and analyzed by using the classical theory of rubber elasticity. Water permeability measurements were also performed to detect the presence of micropores and to determine the type of water transport. It has been shown that it's possible, using different types and amounts of additives, to obtain a wide range of physical properties of swollen PHEMA as required for various biomedical applications.
聚甲基丙烯酸 2-羟乙酯（PHEMA）是在不同类型、不同用量的水溶性添加剂存在下聚合制备的，这些添加剂通过在水中溶胀而被去除。已使用经典橡胶弹性理论对溶胀样品的力学性能进行了测量和分析。还进行了水渗透性测量，以检测微孔的存在并确定水传输的类型。结果表明，通过使用不同类型和用量的添加剂，可以根据各种生物医学应用的要求，使溶胀的 PHEMA 具有广泛的物理性能。
