Abstract

A is a polyimide based resin molding composition comprising 100 parts by weight of crystalline polyimide having recurring structural units of the formula (1): ##STR1## and 1.about.50 parts by weight of crystallization accelerators selected from bisimide compounds of specific structure, a mixture of bisimide compounds, and imide based oligomer. The composition remarkably accelerates the crystallization velocity of polyimide of the formula (1), crystallization can be completed within a greatly reduced cooling time after melt processing, and the crystallized polyimide resin has excellent properties.
