甲基丙烯酸甲酯与1-(2-叔丁基过氧异丙基)-3-异丙烯基苯的共聚研究

Studies on the Radical Copolymerization of MMA and tert Butyl 3 isopropenylcumyl Peroxide

讨论了甲基丙烯酸甲酯与１－（２－叔丁基过氧异丙基）－３－异丙烯基苯的共聚行为。通过自由基共聚得到了带过氧侧基的聚合物。通过红外光谱，紫外光谱和凝胶色谱对共聚物进行了表征。用碘量法测定了共聚物中活性氧的含量，并由此测定了两者的竞聚率，ｒＤ１２０＝０．６９±０．０８，ｒＭＭＡ＝０．６３±０．０８。

The copolymerization behaviors of tert-butyl-3-isopropenylcumyl peroxide and MMA were discussed in this papaer. The copolymers with peroxide groups were obtained by free radical copolymerization.The copolymers were characterized by IR spectrum, UV spectrum and GPC. By iodimetry, we also determined the active oxygen content in the copolymers and estimated the reactivity ratio of the two monomers:r D120 =0.69±0.08,r MMA =0.63±0.08.
