    摘要： A composition and process useful to make flexible polyurethane foams and in particular flexible molded polyurethane foams is disclosed. The usage of dipolar aprotic liquids such as DMSO, DMI, sulfolane, N-methyl-acetoacetamide, N,N-dimethylacetoacetamide as well as glycols containing hydroxyl numbers OH#≦1100 as cell opening aides for 2-cyanoacetamide or other similar molecules containing active methylene or methine groups to make a polyurethane foam is also disclosed. The advantage of using cell opener aids results in a) no foam shrinkage; b) lower use levels of cell opener; c) foam performance reproducibility d) optimum physical properties. In addition, combining the acid blocked amine catalyst together with the cell opener and the cell opener aid results in a less corrosive mixture as well as provides a method that does not require mechanical crushing for cell opening.
