摘　　要：用 WAXD、偏光显微镜 (PM)及 DSC研究了聚烯烃弹性体乙烯 - α-烯烃共聚物 (EOCP)对 PA10 10结晶行为的影响。WAXD结果显示纯弹性体 (EOCP)和接枝弹性体 (EOCP- g- MA)对 PA10 10的晶型均不产生影响。PM观察则表明共混体系中 EOCP与 PA10 10的相互作用很弱 ,在 PA10 10结晶过程中 ,大部分 EOCP被排除在球晶之外 ;而接枝 EOCP与 PA10 10存在较强的相互作用 ,大量的 EOCP- g- MA作为成核剂 ,使 PA10 10球晶向细晶化方向发展 ,而且随弹性体含量的增多而加强。DSC分析证实了接枝EOCP以异相成核剂的方式促进了 PA10 10的结晶 ,尤其是促进了 PA10WAXD, PM and DSC have been used to investigate the crystal behavior of PA1010 blended with EOCP or EOCP g MA elastomer. Whether EOCP or EOCP g MA had no influence on the crystal structure of PA1010 unit cell. PM observation shows that EOCP is excluded from PA1010 spherocrystals and has little effect on the formation of PA1010 spherocrystal, but EOCP g MA functions as a nucleating agent to cause the formation of small spherocrystal of PA1010. The analysis of DSC date further verifies that the EOCP g MA elastomer functions as nucleating agent to promote the crystallization, especially the high temperature crystallization of PA1010.
