甲基丙烯酸缩水甘油酯与甲基丙烯酸氯乙酯共聚反应竞聚率的研究

Studies of Reactivity Ratios of Copolymerization of Glycidyl Methacrylate with 2-Chloroethyl Methacrylate

摘要: 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。

Abstract: Glyidyl methacrylate, 2-chloroethyl methacrylate, their copolymer were synthesized. The two monomer contents in copolymer were determined by ~1H-NMR spectroscopy. Reactiovity ratios of monmers were evaluated by using Fingeman-Ross and Kelen-Tudos methods
