摘要: 用高效液相色谱跟踪2-甲基-7-亚甲基-1,4,6-三氧螺4,4壬烷(MMTN)与丙烯腈(AN),丙烯酸甲酯(MA)的共聚合反应。根据Lowry-Meyer共聚积分方程式,采用插值法进行数据拟合测定单体的竞聚率。对于体系MMTN(M_1)-AN(M_2),r_1=0.048;r_2=0.213;MMTN(M_1)-MA(M_2)r_1=0.025,r_2=0.764。说明两组共聚体系均有较强的交替共聚趋势。Abstract: The copolymerization of 2--methyl--7--methylene--1,4, 6,--trioxaspiro(4,4) nonane (MMTN) with acrylonitrile (AN), methyl acrylate (MA) was fol-lowed by high pressure liquid chromatography.
