Abstract
This invention provides novel adducts of cyclic ethylene urea which are useful as permanent press agents. These adducts include acid, polyacid, ester, and multiester derivatives of cyclic ethylene urea and can be produced by the reaction of the cyclic ethylene urea with glyoxylic acid and glyoxylic acid derivatives, specifically ester acetals of glyoxylic acid. Such materials impart a high degree of permanent press properties to cellulose and cellulose/polymer blend fabrics.
