摘　　要：研究了本体法甲基丙烯酸甲酯-N-环己基马来酰亚胺二元共聚体系的组成对共聚物的光学性能、热性能及力学性能的影响。实验结果表明,当N-环己基马来酰亚胺用量为甲基丙烯酸甲酯量的2·5%时,共聚物的玻璃化转变温度比纯聚甲基丙烯酸甲酯提高了12·3℃;热分解温度提高了41·1℃;硬度及透明性也均有所提高。The influence of the composition of MMA/CHMI copolymer by bulk copolymefization on the transparency, heat resistance and mechanical properties of the copolymer was investigated. The results showed that when the content of CHMI was 2.5 % of that of MMA, the glass transformation temperature and thermal decomposition temperature of the copolymer rose by 12.3℃ and 41.1℃ respectively, compared with the pure PMMA, and the hardness and light transmittance of the copolymer were also increased.
