The mechanical properties of the poly (vinyl chloride) (PVC) and poly (glycidyl methacrylate) [poly (GMA)] blend system and the PVC and poly (hydroxyethyl methacrylate) [poly (HEMA)] blend system and their crosslinked films were investigated. At the same time, the mechanical properties for the corresponding graft copolymers such as PVC‐ g ‐GMA, PVC‐ g ‐HEMA, and their crosslinked films were also investigated in this study. The results showed that the tensile strengths for PVC–poly (GMA) blend systems were higher than those for PVC‐ g ‐GMA graft copolymer, and the tensile strengths for PVC‐ g ‐HEMA were higher than those for PVC‐poly (HEMA) blend systems. However, the mechanical properties for the PVC–poly (GMA) blend system were not affected by the crosslinking of the blend system, but those for PVC‐poly (HEMA) and their graft copolymers decreased with an increase of the equivalent ratio ([NCO]/[OH]) of the crosslinker. Finally, the surface hydrophilicity of the PVC‐ g ‐HEMA graft copolymer and PVC‐poly (HEMA) blends were also assessed through measuring the contact angle. © 1998 John Wiley & Sons, Inc.
