摘　　要：用DSC和WAXD研究了拉伸行为对PA1010/6熔融行为和结晶的影响,发现PA6低含量时拉伸行为使熔点升高,而高含量时使熔点降低,同时拉伸使共聚物熔程增大,ΔHm、ΔSm都增加;拉伸有助于共聚物结晶,使晶粒尺寸和晶面间距增加,结晶度上升.The effect of extension on fusion and crystallization of PA1010/6 is studied by DSC and WAXD, and it is found that the melting-point rises at low content of PA6 and descends at high content, and that melting temperature range expands, and that △Hm and △Sm rises. It is also found that the extension improves crystallization and crystallinity, and that the grain size and the interplanar spacing grow up.
