| 摘 要： | 借助原子力显微镜、偏光显微镜和差示扫描量热仪,研究了山梨糖醇类成核剂对线型低密度聚乙烯(LLDPE)晶体形态及结晶行为的影响。结果表明:随着成核剂用量的增加,LLDPE的晶体形态呈均一化,球晶尺寸逐渐减小;成核剂的加入导致了LLDPE结晶温度和结晶度的提高。

| Abstract: | The effects of sorbitol nucleating agent on crystal morphology and crystallization behavior of LLDPE were studied by AFM,POM and DSC.The results show that:with the increase of use amount of nucleating agent,the crystal morphology of LLDPE becomes uniform,the spherulite size becomes smaller;the addition of nucleating agent increases the crystallization temperature and crystallinity of LLDPE. |
