| 摘 要： | 用电子显微镜（ＴＥＭ、ＳＥＭ），研究了填加刚性粒子对ＰＶＣ／ＣＰＥ体系力学性能和形态的影响。结果发现，刚性粒子的加入，对体系的增韧效果明显。尤其在＂脆－韧＂转变区，促使二元体系产生网丝，使网丝结构变细、变密，促进＂脆－韧＂转变提前发生。ＳＡＮ与ＣＰＥ有较好的相容性，成网络结构分布，ＳＡＮ以粒子形式分散分布，拉伸时发生＂冷拉＂，产生大形变，使基体屈服，体系韧性提高。

| Abstract: | The modification of PVC/CPE blend with rigid organic fillers(ROF) and the toughening mechanism were studied with TEM and SEM. The obvious toughening effect was obtained by adding ROF to PVC/CPE matrix, and some silk formed on the broken surface of samples, and CPE was distributed in form of network structure in PVC matrix, and ROF in form of particles. The cold drawing of ROF occurred and the character of brittle--ductile transformation of matrix was obvious when the samples were stretched so that the toughness of the blends was increased. |
