Effect of Ester Side Chain Structure on the Compatibility of Acrylic Polymer Latex and Natural Rubber

  • 摘要: 制备了5种具有不同烷基数目与链段长度的丙烯酸酯聚合物,将它们按照不同添加量(w=5%,10%,15%)分别添加到天然乳胶中,研究酯侧链结构对丙烯酸酯聚合物与天然乳胶共混相容性的影响。结果表明,当丙烯酸聚合物质量分数为10%时,酯侧链烷基数目最多、链段最长的聚合物所改性的乳胶薄膜的拉伸强度、撕裂强度、硬度和断裂伸长率最大,并具有最小的拉伸永久变形。表征测试进一步证实聚合物酯侧链上烷基数目越多、链段越长,改性薄膜表面越趋于平整和光滑,其薄膜断面变得致密而无析出物,共混薄膜的玻璃化转变温度也逐渐升高,说明共混物两相间相互扩散程度不断增强。实验获得一种具有优良性能的改性薄膜材料。
