Process for preparing triketoimidazolidines |
| abstract |
A modified N,N'-substituted 2,4,5-triketoimidazolidine containing polycarboxylic acid amide or imide groups at least in the main chain, a process for its manufacture which comprises reacting at a temperature of from minus 20 to plus 280° C (a) at least one oxamidic ester having the group --NH--CO--CO--OR v , wherein R v is an aliphatic hydrocarbon group having up to 18 carbon atoms, a cycloaliphatic hydrocarbon group with up to 8 carbon atoms, a mononuclear aromatic hydrocarbon group which may contain at least one hydrocarbon group which constitutes a total of up to 14 carbon atoms (b) at least one isocyanate having or yielding 1 to 4 isocyanate groups or isocyanates forming compound and (c) a polybasic carboxylic acid component having 4 to 71 carbon atoms and 2 to 6 carboxylic groups so as to obtain a condensation product possessing amide or imide groups. |
