    摘要： Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

    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.
