Abstract

A flame retardant blend comprises at least first and second halogenated non-polymeric phenyl ethers having the general formula (I): wherein each X is independently Cl or Br, each m is independently an integer of 1 to 5, each p is independently an integer of 1 to 4, n is an integer of 1 to 5 and wherein the values of n for the first and second ethers are different.

Claims (30)

1. A flame retardant polymer composition comprising:

(a) a polystyrene resin, and

(b) between about 5 and about 25 wt % based on the weight of the polymer composition of a flame retardant blend comprising halogenated non-polymeric phenyl ethers of general formula (I):

wherein X is Br, each m is independently an integer of 1 to 5, each p is independently an integer of 1 to 4, and n is an integer of 1 to 5,

wherein said flame retardant blend comprises at least a first, second, and third ether of general formula (I) wherein the value of n for the first ether is 1, the value of n for the second ether is 2, the value of n for the third ether is 3, and at least one non-terminal phenyl group of the first, second, and third ether of general formula (I) is connected to two phenoxy groups in the 1,4-positions,

wherein the blend comprises about 30 wt % to about 60 wt % of said first ether, about 30 wt % to about 60 wt % of said second ether, and about 1 wt % to about 15 wt % of said third ether,

wherein the halogen content of each halogenated non-polymeric phenyl ether is in the range of about 65 to about 80 wt % of the ether.

2. The composition of claim 1 , wherein, in formula I, n is an integer of 1 to 3.

3. The composition of claim 1 , wherein the bromine content of the flame retardant blend is in the range of about 79 wt % to about 80 wt % of the blend.

4. The composition of claim 1 , wherein the flame retardant blend comprises 5 wt % to 12 wt % of said third ether.

5. The composition of claim 4 , wherein the flame retardant blend comprises 44 wt % to 48 wt % of said first ether, 44 wt % to 47 wt % of said second ether and 5 wt % to 12 wt % of said third ether.

6. The composition of claim 1 , wherein the flame retardant blend comprises about 42 wt % to about 48 wt % of said first ether, about 42 wt % to about 48 wt % of said second ether and about 8 wt % to about 12 wt % of said third ether.

7. The composition of claim 1 , wherein the first ether has a 3p configuration, the second ether has a 4 pp configuration and the third ether has a 5 ppp configuration.

8. The composition of claim 5 , wherein the first ether has a 3p configuration, the second ether has a 4 pp configuration and the third ether has a 5 ppp configuration.

9. The composition of claim 6 , wherein the first ether has a 3p configuration, the second ether has a 4 pp configuration and the third ether has a 5 ppp configuration.

10. The composition of claim 7 , wherein the bromine content of each halogenated non-polymeric phenyl ether is in the range of about 65 to about 80 wt % of the ether.

11. The composition of claim 8 , wherein the bromine content of each halogenated non-polymeric phenyl ether is in the range of about 65 to about 80 wt % of the ether.

12. The composition of claim 9 , wherein the bromine content of each halogenated non-polymeric phenyl ether is in the range of about 65 to about 80 wt % of the ether.

13. The composition of claim 7 , wherein the bromine content of the flame retardant blend is in the range of about 79 wt % to about 80 wt % of the blend.

14. The composition of claim 8 , wherein the bromine content of the flame retardant blend is in the range of about 79 wt % to about 80 wt % of the blend.

15. The composition of claim 9 , wherein the bromine content of the flame retardant blend is in the range of about 79 wt % to about 80 wt % of the blend.

16. The composition of claim 1 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

17. The composition of claim 5 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

18. The composition of claim 6 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

19. The composition of claim 7 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

20. The composition of claim 8 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

21. The composition of claim 9 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

22. The composition of claim 13 , wherein the polystyrene resin high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

23. The composition of claim 14 , wherein the polystyrene resin comprises high impact polystyrene and/or poly (acrylonitrile butadiene styrene).

24. The composition of claim 15 , wherein the polystyrene resin high impact polystyrene and/or poly (acrylonitrile butadiene styrene).
