摘　　要：采用偏光显微镜、差示扫描量热仪和傅里叶变换红外光谱仪等方法研究了降冰片烯二羧酸锌(NED-Zn)和ZnO成核剂对聚(1-丁烯)结晶及晶型转变的影响,并用Jeziorny法分析了聚(1-丁烯)的非等温结晶过程。结果表明,2种成核剂的加入使得聚(1-丁烯)的结晶温度升高、结晶速率加快,NED-Zn的成核效果优于ZnO。NED-Zn和ZnO成核剂的存在加快了PB的Ⅱ-Ⅰ晶型转变,使Ⅱ-Ⅰ半转变时间由39.2 h分别缩短至8.1 h和19.2 h。The effects of NED-Zn and ZnO nucleating agents on the crystallization and crystal transformation of poly(1-butene)were studied by POM,DSC and FT-IR,and the non-isothermal crystallization process of poly(1-butene)was analyzed by Jeziorny method.The results show that the addition of the two nucleating agents increases the crystallization temperature of poly(1-butene)and accelerates the crystallization rate,Among them,the nucleation effect of NED-Zn is better than that of ZnO.The presence of NED-Zn and ZnO nucleating agents accelerates theⅡ-Ⅰcrystal transformation of PB,shortening the half transition time ofⅡ-Ⅰfrom 39.2 h to 8.1 h and 19.2 h,respectively.
