Abstract

An arylalkenyl ether oligomer is produced by the reaction of a polyhaloalkene with a polyhydroxyaryl compound. Halogenation of the resultant oligomer produces a flame retardant having both aromatic and aliphatic bromine groups.

Claims (13)

1. A flame retardant halogenated aryl ether oligomer produced by halogenation of the reaction product of a polyhaloalkene with a halogenated polyhydroxyaryl compound.

2. The flame retardant of claim 1 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is a halogenated dihydroxyaryl compound.

3. The flame retardant of claim 1 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is brominated.

4. The flame retardant of claim 1 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is a halogenated bisphenol compound.

5. The flame retardant of claim 1 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product comprises tetrabromobisphenol A.

6. The flame retardant of claim 1 wherein the polyhaloalkene used to produce said reaction product comprises 1,4-dibromo-2-butene or 1,4-dichloro-2-butene.

7. A flame-retardant resin composition comprising a base resin and a flame retardant halogenated aryl ether oligomer produced by halogenation of the reaction product of a polyhaloalkene with a halogenated polyhydroxyaryl compound.

8. The resin composition of claim 7 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is a halogenated dihydroxyaryl compound.

9. The resin composition of claim 7 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is brominated.

10. The resin composition of claim 7 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product is a halogenated bisphenol compound.

11. The resin composition of claim 7 wherein the halogenated polyhydroxyaryl compound used to produce said reaction product comprises tetrabromobisphenol A.

12. The resin composition of claim 7 wherein the polyhaloalkene used to produce said reaction product is 1,4-dibromo-2-butene or 1,4-dichloro-2-butene.

13. The resin composition of claim 7 wherein the base resin comprises at least one of a polyolefin and a polystyrene.
