Abstract: The color qualities of low density polyurethane foams produced with certain flame retardants is improved by reducing scorch through incorporation of a mixture of diphenyl p-phenylenediamine and the reaction product of diphenylamine and acetone into the foam. The mixture can be employed by admixing with the flame retardant from about 0.5 to about 5.0 percent of said mixture by weight of the flame retardant. The weight ratio of diphenyl p-phenylenediamine to the reaction product of diphenylamine and acetone is from about 1:20 to about 20:1.

Abstract: The invention disclosed relates to a new fabric softener foam having improved utility for softening textile fabrics in either a standard or automatic clothes dryer as well as in an automatic washer.

Abstract: Stable mixtures, comprising a sucrose-based polyol, a .beta.-haloalkyl phosphate or .beta.-haloalkyl phosphonate flame retardant and a hydroxylamine catalyst are provided which are characterized by prolonged shelf life. The stable mixtures are used in the preparation of foamed urethane polymers by reaction thereof with an isocyanate. The urethane polymers are useful as flexible foam insulating material in buildings, pipe lines, storage tanks and refrigerators and as flexible foams in cushions, mattresses, carpet backings, and packaging materials.

Abstract: This invention relates to a non-flammable homogeneous or foamed organo-red mud polymers, which essentially comprise the reaction product of red mud and a compound possessing at least two isocyanate groups.
