摘　　要：甲基丙烯酸三丁基锡酯共聚甲基丙烯酸甲酯的竞聚率测定方法准确性探讨赵秉熙陈文明陈道勇阎立峰（中国科学技术大学应用化学系合肥２３００２６）朱清仁（中国科学院结构成分开放实验室合肥２３００２６）韩哲文陆志豹（华东理工大学材料科学系上海２００２３７）关键词...Five methods were used to measure the reactivity ratios of copolymerization of Tributyltin Methacrylate with MMA.The mean error was gotten from the duplicate exper iments and the 95% credible regions of the reactivity ratios were drawn by the RREVM computer software.Through comparation of credible regions,the evaluation of the accuracy of methods is given.Copolymers PTBTM co MMA were prepared by radiation copolymerization which is radical reaction.The result shows that the method of element analysis and UV or AAS all of these can use to measure the reactive ratios of this copolymer precisely.We made a comparison by the RREVM computer software and discovered the method of UV and element analysis is the best method,but AAS is better than other methods.So we found some better methods than the reference says.
