Claims
- 1. A moisture curable polymer composition comprising,(a) a polydiolefin polymer containing olefinic unsaturation in the main polymer backbone or a polydiolefin polymer containing olefinic unsaturation in pendent side chains; and (b) a silicon cross-linking compound containing at least one easily hydrolyzed substituent and at least one hydride substituent.
- 2. The composition of claim 1 wherein the polydiolefin polymer has a molecular weight up to about 100,000.
- 3. The composition of claim 1 wherein the polydiolefin polymer is polybutadiene having a molecular weight up to about 100,000.
- 4. The composition of claim 1 additionally containing a polysiloxane terminated with hydrolyzable groups.
- 5. The composition of claim 1 wherein the cross-linking compound has the general formula wherein X is a hydrolyzable group and Y may be either substituted or unsubstituted alkyl, substituted or unsubstituted aryl or a hydrolyzable group.
- 6. The composition of claim 5 wherein the hydrolyzable group is chloro, alkoxy or acyloxy.
- 7. The composition of claim 1 which is curable at about room temperature.
- 8. The composition of claim 1 which is curable at a temperature of about 0° F. to 100° F.
- 9. A method which includes exposing a moisture curable polymer composition comprising(a) a polydiolefin polymer containing olefinic unsaturation in the main polymer backbone or a polydiolefin polymer containing olefinic unsaturation in pendent side chains; (b) and a silicon cross-linking compound containing at least one easily hydrolyzed substituent and at !east one hydride substituent; to moisture to cross-link.
- 10. The method of claim 9 wherein the polydiolefin has a molecular weight up to about 100,000.
- 11. The method of claim 9 wherein the polydiolefin is polybutadiene having a molecular weight up to about 100,000.
- 12. The method of claim 9 wherein the composition additionally contains a polysiloxane terminated with hydrolyzable groups.
- 13. The method of claim 9 wherein the cross-linking compound has the general formula wherein X is a hydrolyzable group and Y may be either substituted or unsubstituted alkyl, substituted or unsubstituted aryl or a hydrolyzable group.
- 14. The method of claim 13 wherein the hydrolyzable group is chloro, alkoxy or acyloxy.
- 15. The method of claim 9 wherein the cross-linking is carried out at a temperature of from about 0° F. to 100° F.
- 16. The method of claim 9 wherein the cross-linking is carried out at about room temperature.
