Due to C=C in the rubber structure, polymer/rubber blends have poor thermal and oxidative resistance. In this research, the mechanical and physical properties including the morphology of poly(methyl methacrylate-co-styrene) sheet modified by blending with hydrogenated natural rubber were investigated. The optimum styrene content in copolymer sheets for improving the mechanical properties was 20% (w/w) and inclusion of hydrogenated natural rubber at 1% (w/w) exhibited a higher thermal resistance. This implies that hydrogenated natural rubber can be used as an impact modifier and thermal resistance improver for acrylic plastics.Mahidol UniversityMaterials ScienceArticleSCOPUS10.1177/0095244309345407
