Abstract
The disclosure includes brominated alkenyl alcohols, their use as a flame retardant in polyurethane and polyurethane foams, and polyurethanes containing the brominated alkenyl alcohols. Compositions, methods, and processes are disclosed. The brominated alkenyl alcohols used as flame retardants in polyurethanes can be generally described by Formula (I), the scope of which is disclosed herein.
Claims18

- R3, R4, R5 and R6 are each independently H, C1-C8alkyl, C2-C8 alkenyl, C1-C8 haloalkyl or C2-C8 haloalkenyl;
- R7 is H, C1-C8 alkyl, C2-C8 alkenyl, C1-C8 haloalkyl, or C2-8 haloalkenyl;
- n=1-4;
- m=1-4;
- and
- the compound of Formula 1 is chemically bonded in the polyurethane foam through at least one hydroxyl group on the compound.
