摘要

通过与橡胶共混，提高了脆性聚合物的力学性能。由于橡胶结构中的C=C，聚合物/橡胶共混物的耐热性和抗氧化性较差。研究了与氢化天然橡胶共混改性的聚甲基丙烯酸甲酯-co-苯乙烯片材的力学和物理性能，包括形貌。改善共聚物片材力学性能的最佳苯乙烯含量为20% (w/w)，氢化天然橡胶的掺入量为1% (w/w)时具有较高的耐热性。这意味着氢化天然橡胶可以作为丙烯酸塑料的抗冲击改性剂和耐热性改进剂

Poly(Methyl Methacrylate-co-Styrene) Modified with Hydrogenated Natural Rubber

The mechanical properties of brittle polymers are improved by blending with rubbers. 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

期刊介绍： The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
