Abstract

A universal bonding agent to improve binder-filler adhesion in composite pellants having the formula: ##STR1## wherein R is ##STR2##

Claims

1. In a composite propellant, the improvement comprising the inclusion, in an effective amount, of a bonding agent represented by the formula:

##STR5## wherein R is selected from the class consisting of ##STR6## and x is from 1 to 5.

2. The composite propellant of claim 1 wherein the bonding agent is added in an amount of from about 0.10 to about 5.0 percent of the total propellant weight.

3. The composite propellant of claim 2 wherein the bonding agent is added in an amount of from 0.15 to 1.0 percent of the total propellant weight.

4. The composite propellant of claim 3 wherein the bonding agent is added in an amount of from 0.15 to 0.30 percent of the total propellant weight.

5. The composite propellant of claim 2, 3, or 4 wherein X is 2 or 3.

6. The composite propellant of claim 1 wherein R is --(CH₂)_x OH.

7. The composite propellant of claim 6 wherein the bonding agent is added in an amount of from about 0.10 to about 5.0 percent of the total propellant weight.

8. The composite propellant of claim 7 wherein the bonding agent is added in an amount of from 0.15 to 1.0 percent of the total propellant weight.

9. The composite propellant of claim 8 wherein the bonding agent is added in an amount of from 0.15 to 0.30 percent of the total propellant weight.

10. The composite propellant of claim 6, 7, 8, or 9 wherein x is 2 or 3.

11. The composite propellant of claim 1 wherein R is -(CH₂)_x COOH.

12. The composite propellant of claim 11 wherein the bonding agent is added in an amount of from about 0.10 to about 5.0 percent of the total propellant weight.

13. The composite propellant of claim 12 wherein the bonding agent added in an amount of from 0.15 to 0.30 percent of the total propellant weight.

14. The composite propellant of claim 13 wherein the bonding agent in an amount of from 0.15 to 0.30 percent of the total propellant weight.

15. The composite propellant of claim 11, 12, 13, or 14 wherein x is 2 or 3.

16. The composite propellant of claim 1 wherein R is -(CH₂)_x SH.

17. The composite propellant of claim 16 wherein the bonding agent is added in an amount of from about 0.10 to about 5.0 percent of the total propellant weight.

18. The composite propellant of claim 17 wherein the bonding agent is added in an amount of from 0.15 to 1.0 percent of the total propellant weight.

19. The composite propellant of claim 18 wherein the bonding agent is added in an amount of from 0.15 to 0.30 percent of the total propellant weight.

20. The composite propellant of claim 16, 17, 18, or 19 wherein x is 2 or 3.

21. The composite propellant of claim 1 wherein R is ##STR7##

22. The composite propellant of claim 21 wherein the bonding agent is added in an amount of from about 0.10 to about 5.0 percent of the total propellant weight.

23. The composite propellant of claim 22 wherein the bonding agent is added in an amount of from 0.15 to 1.0 percent of the total propellant weight.

24. The composite propellant of claim 23 wherein the bonding agent is added in an amount of from 0.15 to 0.30 percent of the total propellant weight.

25. The composite propellant of claim 21, 22, 23, or 24 wherein x is 2 or 3.
