Abstract
The novel imidated copolymer of indene or the polymerizable component of naphtha oil and maleimide and, if necessary, maleic anhydride is useful as a resin improver and a compatibilizing agent for the purpose of improving heat resistance and mechanical properties. Another novel imidated copolymer prepared by applying copolymerization of other polymerizable component to the polymerization process is useful as a resin improver and a compatibilizing agent in which, in addition to the above characteristic properties, melting temperature can be designed to a given level.
