摘　　要：研究了甲基丙烯酸甲酯-N-环己基马来酰亚胺-苯乙烯和甲基丙烯酸甲酯-N-环己基马来酰亚胺-丙烯腈两种三元共聚体系中,单体用量对共聚物玻璃化温度和溶度参数的影响。结果表明,苯乙烯、丙烯腈的加入能提高N-环己基马来酰亚胺的反应活性。共聚物的玻璃化温度随着N-环己基马来酰亚胺用量的增加升高,随着苯乙烯用量的增加先升高后降低,而随着丙烯腈用量的增加降低。共聚物的溶度参数随着N-环己基马来酰亚胺用量的增加增大,而随着苯乙烯、丙烯腈用量的增加降低。The influence of the content on the glass transition temperature and of monomer in MMA-CHMI-St and MMA-CHMI-AN systems solubility parameter was studied. The results showed that with the addition of St and AN, the activity of CHMI was enhanced. And the glass transition temperature of copolymers increased with the increase of the content of CHMI, increased firstly and then decreased with the increase of the content of St while decreased with the increase of the content of AN. The solubility parameter of copolymers increased with the increase of the content of CHMI, but decreased with the increase of the content of St and AN.
