Abstract

Plastic compositions containing elastomers and bis-phenoxy compounds having the formula: ##STR1## WHEREIN Z is bromine, m and m'"'"' are each integers having a value of 1-5 and alkylene is a straight or branched chain alkylene group having 1 to 6 carbon atoms.

Claims

1. A plastic composition comprising an elastomer having incorporated therein an effective amount of a bis-phenoxy compound, which functions as a flame retardant for said composition, having the formula ##STR6## wherein (a) Z is bromine;

(b) m and m'"'"' are independent and are integers having a value of from 1 to 5; and

(c) alkylene is a straight or branched chain alkylene group having from one to six carbon atoms.

2. The composition as set forth in claim 1 wherein the amount of said bis-phenoxy compound employed is from about 5% to about 25% by weight, based on the total weight of said composition.

3. The composition as set forth in claim 2 wherein the alkylene group is CH₂.

4. The composition as set forth in claim 2 wherein the alkylene group is (CH₂)₂.

5. The composition as set forth in claim 2 wherein the alkylene group is (CH₂)₃.

6. The composition as set forth in claim 2 wherein the alkylene group is (CH₂)₄.

7. The composition as set forth in claim 2 wherein the alkylene group is ##STR7##

8. The composition as set forth in claim 2 wherein the alkylene group is ##STR8##

9. The composition as set forth in claim 2 wherein the alkylene group is ##STR9##

16. The composition of claim 1 wherein the elastomer is an ethylene propylene diene monomer rubber.

10. A plastic composition comprising an elastomer having incorporated therein an effective amount of a bis-phenoxy compound, which functions as a flame retardant for said composition, having the formula ##STR10##

12. The composition as set forth in claim 10 wherein there is also present a flame retardant enhancing agent which promotes a cooperative effect with said bis-phenoxy compound to increase the flame retardancy of said composition.

13. The composition as set forth in claim 12 wherein said enhancing agent is antimony trioxide.

17. The composition of claim 12 wherein the elastomer is an ethylene propylene diene monomer rubber.

11. A plastic composition comprising an elastomer having incorporated therein an effective amount of a bis-phenoxy compound, which functions as a flame retardant for said composition, having the formula ##STR11##

14. The composition as set forth in claim 11 wherein there is also present a flame retardant enhancing agent which promotes a cooperative effect with said bis-phenoxy compound to increase the flame retardancy of said composition.

15. The composition set forth in claim 14 wherein said enhancing agent is antimony trioxide.
