本文合成了甲基丙烯酸缩水甘油酯、甲基丙烯酸氯乙酯和甲基丙烯酸缩水甘油酯与甲基丙烯酸氯乙酯共聚物。用~1H-NMR谱仪测定了共聚物中两种单体的含量。用Fineman-Ross和Kelen-Tilds两种作图方法以及最小二乘法对单体的竞聚率进行估假。结果表明了甲基丙烯酸氯乙酯的竞聚率(r_1)和甲基丙烯酸缩水甘油酯的竞聚率(r_2)分别为r_1=0.712,r_2=1.081。
In this paper, glycidyl methacrylate, chloroethyl methacrylate and glycidyl methacrylate and chloroethyl methacrylate copolymer were synthesized. The content of the two monomers in the copolymer was measured by ~ 1H-NMR spectrometer. Fineman-Ross and Kelen-Tilds two mapping methods and the least square method of monomer reactivity ratio assessed false. The results showed that the reactivity ratio (r_1) and glycidyl methacrylate (r_2) of chloroethyl methacrylate were r_1 = 0.712 and r_2 = 1.081, respectively.
