Claims
- 1. A novel moisture curable polymer composition comprising, a member selected from the group consisting of polydiolefin polymer containing olefinic unsaturation in either the main polymer backbone or in pendent side chains; and a loop polymer having a polymeric backbone and a plurality of olefinic grbups which have been converted to closed loops by reaction with difunctional organic compounds reactive with said olefinic groups, said olefinic groups from which the loops are formed may either be present within the backbone and/or pendent from the polymeric backbone; and a silicon cross-linking compound containing at least one easily hydrolyzed substituent and at least one hydride substituent.
- 2. The combination of claim 1 wherein the polydiolefin is polybutadiene.
- 3. The composition of claim 2 additionally containing a polysiloxane terminated with hydrolyzable groups.
- 4. The combination of claim 1 wherein the cross linking agent has the general formula
- 5. The combination of claim 4 wherein the hydrolyzable group is chloro, alkoxy or acyloxy.
- 6. The combination of claim 1 which is curable at about room temperature.
- 7. The method which includes exposing a moisture curable polymer composition comprising a member selected from the group consisting of polydiolefin polymer containing olefinic unsaturation in either the main polymer backbone or in pendent side chains; and a loop polymer having a polymeric backbone and a plurality of olefinic groups which have been converted to closed loops by reaction with difunctional organic compounds reactive with said olefinic groups, said olefinic groups from which the loops are formed may either be present within the backbone and/or pendent from the polymeric backbone; and a silicon cross-linking compound containing at least one easily hydrolyzed substituent and at least one hydride substituent to moisture to cross-link.
- 8. The method of claim 7 wherein the polydiolefin is polybutadiene.
- 9. The method of claim 8 wherein the composition additionally contains a polysiloxane terminated with hydrolyzable groups.
- 10. The method of claim 7 wherein the cross linking agent has the general formula
- 11. The method of claim 10 wherein the hydrolyzable group is chloro, alkoxy or acyloxy.
- 12. The method of claim 7 wherein the cross-linking is carried out at about room temperature.
- 13. A substrate having an adherent coating thereon which is a moisture cured polymer composition comprising a member selected from the group consisting of a polydiolefin polymer containing olefinic unsaturation in either the main polymer backbone or in pendent side chains; and a loop polymer having a polymeric backbone and a plurality of olefinic groups which have been converted to closed loops by reaction with difunctional organic compounds reactive with said olefinic groups, said olefinic groups from which the loops are formed may either be present within the backbone and/or pendent from the polymeric backbone; and a silicon cross-linking compound containing at least one easily hydrolyzed substituent and at least one hydride substituent.
- 14. The substrate of claim 13 wherein crosslinking occurs about room temperature.
