ABSTRACT:
An aromatic polythioetherimide having a recurring unit of the following general formula (II): ##STR1## wherein --Ar--, which may be the same or different in the polymer, each represents a divalent aromatic residue and ##STR2## which may be the same or different in the polymer, each represents ##STR3## The aromatic polythioetherimides can be melt-molded, are excellent in the balance of mechanical properties and heat resistance, and can be widely used for parts in the electric and electronic fields, housings, automobile parts, aircraft interior parts, sliding parts, gears, cams, insulating materials, heat-resistant films, heat-resistant varnishes, heat-resistant fibers, etc., and preferably can be used as an engineering plastic for gears, cams, etc., and a heat-resistant insulating film material for electronic hardwares.
