A series of new crosslinked copoly(urethane-methacrylate)s (CPUAs) were synthesized by the polymerization of new urethanemethacrylate macromonomers with double bonds at the end of the chain, which were prepared from isophorone diisocyanate, -hydroxyethyl methacrylate, different content of poly(1,2-propanediol ortho-phthalate) (PPP), and poly(ethylene glycol) 600. The properties of CPUAs were measured by dynamic mechanical analysis, thermogravimetric analysis, wide-angle X-ray diffraction, water uptake, and optical properties testing, and mechanical performance measurements. The results revealed that the greater PPP contents in the CPUAs lead to the higher glass transition temperature, hardness, lower thermal stability, and water uptake. Obtained CPUAs present the good transparence. (c) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
