Abstract
Included are mondiol haloneocarbyl polyethers and their esters incorporated in polyurethane foams. The compositions have haloneocarbyl moieties, and in general, the polyethers before the incorporation in the polyurethanes contain from one to two hydroxy moieties. The polyurethane foam compositions are flame-retardant and can have little or no scorch and little or no odor.
Claims22
A flame-retardant, substantially non-scorching polyurethane foam prepared using a composition comprising an organic polyisocyanate, a polyahl and a flame-retarding amount of a mondiol haloneocarbyl polyether or an ester capped derivative of such polyether, said mondiol haloneocarbyl polyether being represented by the general formula:
- H(O--R[Y).sub.n' (X).sub.n (Y).sub.n' ].sub.n" --R.sup.1
- wherein
- HO--R is a hydro(oxyhaloeocarbyl) moiety;
- R.sub.1 is separately at each occurrence hydrogen or C.sub.1-20 organic moiety;
- X is separtely at each occurrence halogen-containing 1,1,2,2-tetra-substituted ethoxy;
- Y is separately at each occurrence 1,1,2,2-tetra-substituted ethoxy not containing halogen;
- n is an integer from zero to about 20;
- n' is an integer from zero to about 20;
- and
- n" is separately at each occurrence a number from one to about 20.
