<p>The first invention relates to a process for preparing an epoxidized organic polymer by dispersing or suspending a solid organic polymer in an organic solvent and epoxidizing the dispersed or suspensed polymer with a peroxide. The epoxidized polymer thus obtained is usable for coating materials, resin modifiers, rubber modifier or adhesives, thus being extremely useful. The second invention relates to a thermoplastic resin composition improved in mechanical strengths and comprising a thermoplastic resin, an epoxidized EPDM and an acid anhydride. The third invention relates to a primer composition comprising 100 parts by weight of an epoxidized EPDM and 50 to 70 parts by weight of a product of chlorination of a polyolefin modified with an unsaturated carboxylic acid or an anhydride thereof. The fourth invention relates to an unvulcanized rubber composition comprising an epoxidized EPDM, a diene polymer and a vulcanizing agent and a process for producing rubber moldings by extruding the unvulcanized rubber composition and vulcanizing the extrudate.</p> |
