Abstract

A method for improving a production characteristic of flame-retardant polyurethanes. The characteristic may be selected from the group consisting of PA0 (1) processability; PA0 (2) scorch; PA0 (3) odor; and PA0 (4) flame-retardant efficiency. The method comprises incorporation into a polyurethane an amount effective to reduce combustibility of a haloether phosphorate flame-retardant under conditions sufficient to improve said characteristic. Also, the flame-retardant polyurethane composition such as prepared by said method. Preferably, the polyurethane is a foam, especially a flexible foam and most especially flexible slabstock foam.
