STUDIES ON COPOLYMERIZATION KINETICS OF AMPHIPHILIC ACRYLATE COPOLYMERS

利用过氧化苯甲酰(BPO)为引发剂探讨了甲基丙烯酸β-羟乙酯(HEMA)和丙烯酸十六烷基酯(RA)的自由基共聚合。重点讨论了该共聚反应的动力学方程，求出了这两种单体的竞聚率。并用IR、13C-NMR等手段对共聚物进行了表征。

To search after the distribution law about the chain structure of amphiphilic copolymer, the radical copolymerization of 2-hydroxyethyl methacrylate (HEMA) and aliphatic acrylate was carried out in dioxane at 80 ℃ using benzoyl peroxide as initiator. The study emphasized on the kinetics equation of polymerization. The monomer reactivity ratio was calculated. It was found that the component of HEMA and aliphatic acrylate could distribute uniformly in the course of polymerization If mole ratio of monomer f1 was between 0.4～0.9, and so anticipated copolymer could be acquired by adjusting proportion of the above monomer. The component and structure of copolymers were characterized by IR, 13C-NMR.
