| titleOfInvention | A method of producing new polymetides containing phosphonic groups |
| abstract | 1. A method of producing new polymethides containingnphosphono groups represented by the general formula 1,nwherein R1, R2, R3 and R4 are the same or different and arenhydrogen atom, alkyl group, alkoxy group,na hydroxyl group or an amino group, optionally a groupnamino substituted with acyl groups, characterizednin that one mole part of the aromatic aldehydenof the general formula 3 in which R1, R2, R3 and R4 are suchnalone or different and represent a hydrogen atom, an alkyl group,nan alkoxy group, a hydroxyl group or an amino group,noptionally an amino group substituted with groupsnacyls and R is hydrogen or lowernan alkyl group is reacted with at least onenthe mole fraction of a phosphonylating agent that isnphosphorus trichloride, the reaction being carried out at temperaturen250-400 K, in an organic solvent,nin the presence of at least one mole part of the carboxylic acid,nuntil the reactants react, and thennthe reaction mixture is subjected to extensive hydrolysisnand cationic polymerization with an aqueous acid solutionninorganic acid, preferably hydrochloric acid, is obtainedna solution from which the group-containing polymethide is isolatednPLnphosphonic. |
