氟氯代羧酸与乙炔反应制得氟氯代羧酸乙烯酯,后者分别以过氧化二苯甲酰和三丁基硼为引发剂在不同温度下进行本体聚合。以X-射线衍射图和红外吸收率D_(916)/D_(850)比值观测聚乙烯酯及其水解物聚乙烯醇的立体规整性。不同侧链长度的聚含氟酸乙烯酯的X-射线衍射图并没有反映出高分子链在立体规整性上的差异,但其水解产物聚乙烯醇D_(916)/D_(850)吸收率比值随侧链体积增大而增加、侧基极性效应和空间效应的影响是肯定的。不论是聚乙酸乙烯酯和聚含氟酸乙烯酯聚合温度对它们的立体规整性都没有明显的影响。
Chlorocarbonyl chloroformate is obtained by reaction of chlorofluorocarboxylic acid with acetylene, and the latter is bulk polymerized with dibenzoyl peroxide and tributylboron as initiators respectively at different temperatures. The stereoregularity of polyvinyl alcohol and its hydrolyzed polyvinyl alcohol was observed by the X-ray diffraction pattern and infrared absorption ratio D 916 / D 850. The X-ray diffraction spectra of poly (vinylfluoride acid esters) with different side chain lengths did not reflect the difference in stereoregularity of the polymer chain, but the hydrolyzate poly (vinyl alcohol) D 916 / D 850 absorption rate The ratio increases with increasing side-chain volume, and the effect of pendant polar and spatial effects is positive. Neither polyvinyl acetate nor polyfluorinated acid vinyl ester polymerization temperature had any significant effect on their stereoregularity.
