| titleOfInvention | Method for the production of a new vinyl alcohol-co-N- (aminophenyl) maleimide copolymer |
| abstract | 1. The method of producing a new alcohol copolymern. vinyl-co-N- (ammophenyl) maleimide of formula 57)nm is the number of vinyl alcohol residuesnranging from 0.25 to 3 and n isna degree of copolymerization ranging from 10 to 105, characterizednwith 1 mole of N- (ammophenyl) - copolymernmalelmld with vinyl acetate, with the general formula shownnin figure 2, where m 1 n are highernas indicated, 1 to 0.2 to 3 moles of hydrated acidnp-toluenesulfonic acid is dissolved in 200 ton3 000 cm3 of tetrahydrofuran or dioxane,n2. The method of producing a new alcohol copolymernvinyl-? -N- (ammophenyl) maleimide of the general formulan2, where m is the number of vinyl alcohol residuesnranging from 0.25 to 3 and n isna degree of copolymerization ranging from 10 to 10, characterizednwith 1 mole of N- (aminophenyl) - copolymernmaleimide with vinyl acetate, of the general formula I, nanwherein m 1 n are as defined above, 1 from 0.2 to 3nmoles of hydrated p-toluenesulfonic acid are addednup to 200-3000 cm3 of ethanol, which contains from 0.1 to 4%,npreferably 2%, calcium phosphate,. ,n3. The method of producing a new alcohol copolymernvinyl-? -N- (aminophenyl) maleimide of the general formulanin Figure 2, where m denotesnthe amount of vinyl alcohol residues within the limitsnfrom 0.25 to 3 and n is the degree of copolymerizationnranging from 10 to 105, characterized in that 1 mole of a copolymernN- (aminophenyl) maleimide with vinyl acetate, 1ngeneral formula 1, |
