摘　　要：制备了丙烯酸甲酯类杜仲胶合金,采用核磁共振波谱仪以及红外光谱仪确定了丙烯酸甲酯类功能基团的改性,研究了丙烯酸甲酯类功能基团的引入对合金材料结晶性能、极性以及相对分子质量的影响。结果表明,功能基团可成功引入到杜仲胶体系中,聚丙烯酸甲酯/杜仲胶合金仍然具有较高的相对分子质量;在杜仲胶用量固定的情况下,随着丙烯酸甲酯类功能基团的引入,合金的结晶度不断降低直到基本消失,熔点也呈降低趋势。Blends of polymethacrylates and Eucommia ulmoides gum(EUG)were prepared in this manuscript.1H NMR and IR were performed to characterize the modification of methyl acrylate group.The properties of blends were studied,especially the crystallization properties and the molecular weight of the polymer.The results showed that the functional groups were successfully introduced into EUG material with relative high molecular weight,which increased the polarity of materials.The crystallinity of blends gradually deceased and disappeared with the addition of methyl acrylate functional groups under constant amount of EUG.At the same time,the melting point of blends also showed a decreasing trend.
