摘要：
Resin composition composed of 99.9 to 50 % by weight of a polyimide having a repeating unit of the formula as defined below and 0.1 to 50 % by weight of an aromatic polyamideimide are improved in heat resistance and mechanical strength and have the inherent properties of polyimide;
where X indicates a direct bond or is -S- or
and R is a tetravalent radical selected from the group consisting of aliphatic radicals having at least 2 carbon atoms, cycloaliphatic radicals, monocycloaromatic radicals and condensed polycycloaromatic radicals, and uncondensed polycycloaromatic radicals including aromatic radicals interconnected directly or through a cross-linkage.
