| titleOfInvention | Mixtures of alkylated methylolated 4,5-dihydroxy-imidazolidin-2-ones |
| abstract | The present invention provides methylolated 4,5-dihydroxyimidazolidin-2-one (DMDHEU) with monovalent C 1-5 alcohol, ethylene glycol, diethylene glycol, 1,2-propylene glycol, 1,3 -Propylene glycol, 1,2-butylene glycol, 1,3-butylene glycol, 1,4-butylene glycol, glycerol and formula HO (CH 2 CH 2 O) n H (where 3 ≦ n ≦ 20) Reacted with a polyol selected from the group consisting of polyethylene glycols, wherein the monovalent C 1-5 alcohol and polyol are each used in an amount of 0.1 to 2.0 mol equivalents relative to DMDHEU, and the reaction is at a temperature of 20 ° C. to 70 ° C. And a mixture of alkylated methylolated 4,5-dihydroxyimidazolidin-2-ones, characterized in that it is carried out at a pH of 1 to 2.5 and the pH after the reaction is set to a value of 4 to 8. The method is disclosed. |
