摘    要:从内聚能的角度建立了含共聚组成、序列不均匀性的共聚物分子量及分布理论,导出其计算式。将凝胶渗透色谱(GPC)与紫外吸光谱(UV)和示差折光仪(DR)串接,测定苯乙烯(St)/N-苯基马来酰亚胺(PMI)共聚物的分子量。根据St/PMI共聚合原理,对St-PMI共聚物的分子量进行模型化,该模型能较好地预测引发剂、单体配比、转化率对共聚物分子量的影响。

关 键 词:苯乙烯  N-苯基马来酰亚胺  共聚物  分子量测定

Abstract:The molecular weight theory and calculation equation of copolymer were set up after consideration with the influence of composition and sequence distribution. The molecular weight for St/PMI copolymer was investigated by means of GPC connected with DR and UV detectors. From the mechanism of St/PMI copolymerization, a model of molecular weight for St-PMI copolymer was proposed to predicate the effects of initiator concentration, feed fraction and conversion on the molecular weight of St-PMI copolymer. The predicted results coincided with the experimental data.
Keywords:Styrene  N-Phenylmaleimide  Molecular weight of copolymer
