| titleOfInvention | A method of producing new N-halogenophenyl / -maleimides copolymers with vinyl alcohol |
| abstract | 1. The method of producing new copolymersnN- (halogenophenyl) maleimides with alcoholnvinyl, of the general formula 2, wnwhere m is the number of vinyl alcohol residuesnranging from 0.25 to 3, Xnis fluoro or chloro or bromo and n isndegree of copolymerization from 10nto 105, characterized in that 1 mole of the copolymernN- (halogenophenyl) maleimide with vinyl acetate,nof the general formula I and from 0.2 to 3 molesnof hydrated p-toluenesulfonic acidnis dissolved in 200 to 3000 cm 3 of tetrahydrofurannor dioxane or dimethylformamide,nthen heated until completely hydrolyzednacetate groups in the copolymer wna temperature of 293 to 393 K, thennthe product precipitates and separates. |
