A moisture curable composition is described. The composition comprises a member selected from the group consisting 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 the olefinic groups, the olefinic groups from which the loops are formed may either be present within the backbone an/or pendent from the polymeric backbone; and a silicon cross-linking compound containing at least one easily hydrolysed substituent and at least one hydride substituent.
