PVC/CPE és PVC/PMMA blendek mechanikai tulajdonságainak összehasonlítása

Abstract

In this study the mechanical properties of some PVC blends can be determined. Mostly miscibility is the PVC with other polymer to improve their mechanical properties. CPE and PMMA are significantly changes the mixing structure morphology. CPE (chlorinates polyethylene) is commonly used to modify the material toughness. PMMA [poly (methy-methacrylate) is has a significant effect on the impact behaviour of the PVC. Proved the CPE and PMMA have material properties correcting effect. In this paper we compare the mechanical properties of blends, such as: tensile-, impact-, bending- and hardness test. The all test demonstrated the structure changes. Based on the results, the impact test of the PVC blend with PMMA polymer gives information to the rigid structure, the cells morphology could be determined by the tensile test.
