    A polyamide acid composition for preparing a polyimide which can extend the pot life of the composition comprising a solution of a polyamide acid in an organic solvent, the polyamide acid being a precursor of the polyimide, a dehydrating agent, a catalyst and a pot life extending agent which can lower a rate of conversion of the polyamide acid to the plyimide, and the process for preparing the polyimide from said polyamide acid composition. According to the present invention the pot life can be extremely extended to give the composition an enough flowability for a long time without reducing the excellent properties such as a heat resistance and an electric insulation of the obtained polyimide.
    一种用于制备聚酰亚胺的聚酰胺酸组合物,可延长组合物的固化寿命,该组合物包括聚酰胺酸在有机溶剂中的溶液(聚酰胺酸是聚酰亚胺的前体)、脱水剂、催化剂和可降低聚酰胺酸转化为聚酰亚胺的速率的固化寿命延长剂,以及用上述聚酰胺酸组合物制备聚酰亚胺的工艺。根据本发明,可以极大地延长聚酰亚胺的罐装寿命,使该组合物具有足够长的流动性,而不会降低所得聚酰亚胺的优异性能,如耐热性和电绝缘性。

    A polyamide acid composition for preparing a polyimide which is improved in the stability in a form of solution and can extend the pot life of the composition comprising a solution of a polyamide acid in an organic solvent, the polyamide acid being a precursor of the polyimide, and an N-substituted heterocyclic compound as a chemical treating agent which can lower a rate of conversion of the polyamide acid to the polyimide. The pot life can be extremely extended to give the composition an enough flowability for a long time without reducing the excellent properties such as a heat resistance of the obtained polyimide.
