摘要
用小角 X光散射法 ( SAXS)对 ABS树脂 (丙烯腈 A-丁二烯 B-苯乙烯 S) /聚酰胺 6树脂 ( PA6) /苯乙烯 -马来酰亚胺共聚物 ( St-co-NPMI)三元共混体系的界面结构进行了研究 .由 Debye散射理论中相关距离 ( ac)和积分不变量 ( Q)值随组成比变化显示 ,在 ABS/PA6/St-co-NPMI( 70 /3 0 /2 ,wt% )时 ,ac=50 .74 ,Q=0 .3 972体系相容程度较高 .这表明 ,St-co-NPMI使体系的相容性得到改善 ,扫描电镜和 DSC分析结果与 SAXS所得结果一致 .
The interfacial microstructure of ABS/PA6/St co NPMI blends has been studied using Small angle X ray scattering (SAXS). The dispersing degree of the dispersed phases for the blending system was characterized by the values of Debye correlation distance ( a c ) and the integral constant ( Q ). According to the correlation distance of the blending system varying with the phase component of the blends, the compatibility was best for the blending system ABS/PA6/St co NPMI(70/30/2, wt%), here, a c =50.74, Q =0.3972. It shows that the St co NPMI is a good compatibilizer for ABS/PA6 blending system, which correspondent with the results from DSC and SEM.$$$$
