本文采用X——射线衍射法测定了一种新颖的可溶性聚酰胺——酰亚胺PAI的聚集态结构为无定形态结构。广泛试验了PAI在各种溶剂中的可溶性,计算了PAI的溶度参数。并从结构形态和热力学等方面探讨了PAI的可溶性机理。
In this paper, the X-ray diffraction method was used to determine the aggregation structure of a novel soluble polyamide-imide PAI in the amorphous state. The solubility of PAI in various solvents was extensively tested and the solubility parameters of PAI were calculated. The soluble mechanism of PAI was discussed from the aspect of structure and thermodynamics.
