<p>A method is provided for preparing pulverulent olefinmaleic anhydride copolymers from concentrated solutions of olefins and maleic anhydride in organic solvents, by radical polymerization in the presence of dispersants. By the method of invention pulverulent olefin-maleic anhydride copolymers can be prepared with reduced reaction time and with high maleic anhydride conversion, as compared with previously known methods.</p> |
