Claims
- 1. A heat-stable, polymer-forming adhesive composition comprising:
- (a) polymerizable material, an unsaturated polymer containing ethylenic carbon-carbon double bonds;
- (b) a transition metal compound derived from a transition element;
- (c) a polymer chain terminating antioxidant; and
- (d) a preventive antioxidant for decomposing hydroperoxide,
- wherein the resulting composition is a stable, storable, pourable liquid which is curable to a solid polymer on initiation of a curing step.
- 2. A composition as claimed in claim 1 wherein said unsaturated polymer is an unsaturated polyester derived from the condensation of glycols such as ethylene or propylene glycol with fumaric anhydride or maleic anhydride.
- 3. A composition as claimed in claim 1 wherein said transition metal compound is selected from chromium, manganese, nickel, iron, or cobalt metal salts.
- 4. A composition as claimed in claim 3 wherein said transition metal compound is a ferric metal salt.
- 5. A composition as claimed in claim 4 wherein said ferric metal salt is ferric chloride.
- 6. A composition as claimed in claim 1 wherein said polymer chain terminating antioxidant is a p-alkoxyphenol of the formula: ##STR7## wherein R.sub.1 and R.sub.2 are each selected from the group consisting of H, phenyl and t-butyl, and X is alkyl or alkyloxy and said alkyl group containing from 1 to 4 carbon atoms.
- 7. A composition as claimed in claim 6 wherein said p-alkoxyphenol is selected from p-methoxyphenol, 2,6-di-t-butyl-4-methoxyphenol or 2,6-diphenyl-4-methoxyphenol.
- 8. A composition as claimed in claim 1 wherein said preventive antioxidant is a compound of the formula: ##STR8## wherein Y is ##STR9## in which Z is selected from the group consisting of H and NO.sub.2 ; or Y is ##STR10## in which R is alkyl containing from 4-18 carbons.
- 9. A composition as claimed in claim 8 wherein said preventive antioxidant is dilaurylthiodipropionate.
- 10. A composition as claimed in claim 1 which is essentially free of an inert solvent.
- 11. A composition as claimed in claim 1 wherein a photo initiator is included.
- 12. A composition as claimed in claim 1 wherein a thermal initiator is included.
