Claims4
A polymer composition containing a polyurethane and a flame retardant a flame retardant amount of tribromocumene.
A polymer composition of claim 2 wherein said amount of tribromocumene is from about 0.05 to about 40 weight percent of said polymer composition.
A flame retardant, self-extinguishing polyurethane comprising:
- (a) an organic polyol,
- (b) sufficient organic polyisocyanate to combine with said polyol to produce polyurethane,
- (c) a catalyst and
- (d) a sufficient amount of tribromocumene to impart flame retardant properties to the polyurethane.
