采用自由基聚合法合成了的聚反丁烯二酸二特丁酯(PDtBF)、聚反丁烯二酸二异丙酯(PDiPF)、聚反丁烯二酸二仲丁酯(PDsBF)、聚反丁烯二酸二仲戊酯(PDsAF)、聚反丁烯二酸二环已酯(PDCHF)和聚反丁烯二酸甲基异丙基酯(PMiPF)这六种不同的反丁烯二酸酯类聚合物,利用~1H-NMR、~(13)C-NMR等表征手段对上述几种聚合物的链结构进行了分析表征。利用X-射线衍射方法对聚合物的聚集态结构进行了研究,结果表明,上述几种聚合物均具有较高的分子量,并表现出很强的脆性,聚合物的分子链间距随聚合物中酯基体积的增大而增加,对聚合物的热性能等进行了初步研究。
(PDtBF), PDiPF, PDsBF synthesized by the free-radical polymerization method, (PDsAF), PDCHF and PMiPF, six different trans-butyl The ester structure of these polymers was characterized by ~ 1H-NMR and ~ (13) C-NMR. X-ray diffraction method was used to study the aggregated structure of the polymer. The results showed that the above polymers have high molecular weight and exhibit strong brittleness. The molecular chain spacing of the polymer varies with the polymer Increasing the volume of ester groups increases, the thermal properties of the polymer were studied.
