Abstract

A halogenated aryl ether oligomer is formed by halogenation of an aryl ether oligomer and is useful as a flame retardant for flammable macromolecular materials. Typically, the halogenated aryl ether oligomer comprises the following repeating monomeric units: wherein R is hydrogen or alkyl, especially C 1 to C 4 alkyl, Hal is halogen, m is at least 1, n is 0 to 3 and x is at least 2.

Claims (28)

1 . A halogenated aryl ether oligomer formed by halogenation of an aryl ether oligomer.

2 . The oligomer of claim 1 , wherein the halogen content of the halogenated aryl ether oligomer is in the range of about 50 to about 83 wt % of the oligomer.

3 . The oligomer of claim 1 and having an average of least 3 aryl rings.

4 . The oligomer of claim 1 , wherein the halogen is bromine.

5 . The oligomer of claim 1 , wherein the aryl ether oligomer is brominated, comprises at least 5 aryl rings and has a molecular weight up to 1,000,000 Daltons.

6 . The oligomer of claim 1 , wherein the oligomer comprises the following repeating monomeric units:

wherein R is hydrogen or alkyl, especially C 1 to C 4 alkyl, Hal is halogen, m is at least 1, n is 0 to 3 and x is at least 2.

7 . The oligomer of claim 6 , wherein x is 5 to 20.

8 . The oligomer of claim 6 , wherein Hal comprises bromine.

9 . The oligomer of claim 6 , wherein said halogenated aryl ether oligomer also comprises end groups each independently comprising alkyl, alkoxy, aryl, aryloxy, hydrogen, halogen and hydroxyl.

10 . A flame retardant polymer composition comprising (a) a flammable macromolecular material and (b) a halogenated aryl ether oligomer flame retardant formed by halogenation of an aryl ether oligomer.

11 . The composition of claim 10 , wherein the halogen content of the halogenated aryl ether oligomer is in the range of about 50 to about 83 wt % of the oligomer.

12 . The composition of claim 10 and having an average of least 3 aryl rings.

13 . The composition of claim 10 , wherein the halogen is bromine.

14 . The composition of claim 10 , wherein the aryl ether oligomer is brominated, comprises at least 5 aryl rings and has a molecular weight up to 1,000,000 Daltons.

15 . A flame retardant polymer composition comprising (a) a flammable macromolecular material and (b) a halogenated aryl ether oligomer flame retardant formed by halogenation of an aryl ether oligomer, wherein said halogenated aryl ether oligomer comprises the following repeating monomeric units:

wherein R is hydrogen or alkyl, especially C 1 to C 4 alkyl, Hal is halogen, m is at least 1, n is 0 to 3 and x is at least 2.

16 . The composition of claim 15 , wherein x is 5 to 20.

17 . The composition of claim 15 , wherein Hal comprises bromine.

18 . The composition of claim 15 , wherein said halogenated aryl ether oligomer also comprises end groups each independently comprising alkyl, alkoxy, aryl, aryloxy, hydrogen, halogen and hydroxyl.

19 . The composition of claim 15 , wherein the flammable macromolecular material (a) is a thermoplastic polymer or a thermosetting polymer.

20 . The composition of claim 15 , wherein the flammable macromolecular material (a) is polystyrene and the amount of halogenated aryl ether oligomer flame retardant in the composition is between about 5 and about 25 wt %.

21 . The composition of claim 16 , wherein the flammable macromolecular material (a) is polypropylene and the amount of halogenated aryl ether oligomer flame retardant in the composition is between about 20 and about 50 wt %.

22 . The composition of claim 15 , wherein the flammable macromolecular material (a) is polyethylene and the amount of halogenated aryl ether oligomer flame retardant in the composition is between about 5 and about 35 wt %.

23 . The composition of claim 15 , wherein the flammable macromolecular material (a) is a polyamide or polyester and the amount of halogenated aryl ether oligomer flame retardant in the composition is between about 5 and about 25 wt %.

24 . A flame retardant polymer composition comprising (a) a flammable macromolecular material and (b) a halogenated aryl ether having the following formula:

wherein each R 1 is independently selected from hydrogen, hydroxy, halogen and alkyl, wherein each R 2 is independently selected from hydrogen, hydroxy, halogen and alkyl, provided at least one R 2 is halogen, n is 5, m is 4, and x is from 1 to 10.

25 . The composition of claim 24 , wherein x is from 2 to 6.
