Abstract
The present invention is to the production of flexible polyurethane foam in the absence of an amine catalyst. The reactivity of the foam forming system can be controlled by the addition of an autocatalytic polyol containing a tertiary amine where the amount of autocatalytic polyol comprises less than 5 percent by weight of the total polyol.
