| 摘 要： | 通过多步交换反应及扩散－聚合的方法，使聚丙烯酸丁酯被嵌入到改性层状结构的白泥层间，得到白泥－聚丙烯酸丁酯纳米复合物的微米粒子；然后将聚氯乙烯与白泥－聚丙烯酸丁酯进行熔融共混，制得具有一一特性的有机－无机纳米复合材料，并对复合材料的缺口冲击强度及动态力学性能进行了研究，结果表明，白泥－聚丙烯酸酯含量为5．0wt％时，复合材料的力学性能最佳；聚氯乙烯与高含量的白泥－聚丙烯酸丁酯（分别为25．0wt%和50．0wt%）形成的复合材料，在聚氯乙烯的玻璃化转变温度之前，储能模量出现先降低而后增加的过程。

| Abstract: | Layered white bole nanocomposites modified by polyacrylate were prepared with multi step exchange reaction and diffusion polymerization method. PVC is blended meltingly with polyacrylate modifyeding white bole and a series of PVC/modified white bole nanocomposites are obtained. The mechanical properties of PVC/modified white bole nanocomposites have been studied. The notch impact strength and dynamic mechanical properties of composites were studied systematically. The results indicate that the mechanical properties of the nanocomposites are best when the content of white bole PBA is 5.0 wt%, and the storage modulus of the nanocomposites first decrease and then increase before the glass transition temperature of PVC when the content of white bole PBA is 25.0 wt% and 50.0 wt% respectively. |
