| 摘 要： | 本文报道了由60℃自由基引发聚合得到的聚甲基丙烯酸-2,3,3-四氟丙酯,经浓硫酸水解而生成聚甲基丙烯酸。后者以重氮甲烷酯化,转化成聚甲基丙烯酸甲酯,并且分别作红外光谱、核磁共振波谱分析。根据分析结果推断聚甲基丙烯酸-2,2,3,3-四氟丙酯为无规立构聚合物,并与聚甲基丙烯酸正丙酯衍生而来的相应产物作比较。

| Abstract: | The present paper describes the stereoregularity of poly-2, 2, 3, 3-tetrafluoropropyl methacrylate (PTFPMA). PTFPMA is prepared by free radical polymerization with benzoyl peroxide as initiator in toluene at 60℃. Hydrolysis of PTFPMA in concentrated sulfuric acid gave a water soluble polymethacrylic acid, and reesterification with diazomethane grave polymethyl methacrylate. The polymethyl methacrylate was confirmed to be an ataetie polymer by NMR and IR analysis. These results also indieate that PTFPMA is an atactie polymer. |
