【摘要】 以二乙烯基苯为交联剂，由甲基丙烯酸甲酯、苯乙烯、甲基丙烯酸模型浇铸共聚，制备了一种交联型透明材料。系统研究了材料的组成对表面硬度、透光率、冲击强度、热变形温度、密度等性能的影响。结果表明，配比适当时可制得性能优良的新型改性有机玻璃，既提高了表面硬度、冲击强度、热变形温度、玻璃化转变温度，又保持了良好的透光性能。更多还原

【Abstract】 A kind of crosslinked transparent material was prepared by mold copolymerization of methyl methacrylate, Styrene methacrylic acid and divinylbenzene as crosslinking agent. The effects of componets and contents on surface hardness, impact resistance, defromation start temperature, density an so on were systematically studied. The experiment results show that the new modified organic glass has high surface hardness, impact resistance, deformation start temperature and glass transition temperature as well as good transmittancy of visible light.更多还原
