Abstract: | 4,4′-Diaminodiphenylmethane and 1-(p-chlorophenyloxycarbonyl)aziridine gave 1,1′-(methylene-di-p-phenylene)-bis-(1,3-imidazolidine-2-one). The bis-imidazolidinone reacted with formaldehyde or acrylonitrile to give 1,1′-(methylene-di-p-phenylene)-bis-(3-hydroxymethyl-1,3-imidazolidine-2-one) or 1,1′-(methylene-p-phenylene)-bis-[3-(2-cyanoethyl)-1,3-imidazolidine-2-one] respectively. The bis-methylol derivative gave a polycondensation product on standing in dichloroacetic acid. The dicarboxylic acid which was obtained by treating the bis-cyanoethyl derivative with concentrated hydrochlorie acid gave high molecular polyamides having imidazolidinone rings in the polymer chain by the reaction with hexamethylene diamine or m-xylylene diamine. |
