Abstract:
A one-part moisture-curable composition consisting essentially of:(A) 100 parts by weight of a saturated hydrocarbon polymer having on average at least 1.5 hydrolyzable silyl groups in its molecule and at least 50 mole percent of repeat units of said saturated hydrocarbon polymer are isobutylene units;(B) 10 to 300 parts by weight of a silicon-free conduit compound having at least one C.sub.6 to C.sub.30 hydrocarbon group in its molecule, said compound being selected from the group consisting of(i) esters,(ii) ethers,(iii) epoxy-containing compounds,(iv) anhydrides and(v) ketones; and(C) a sufficient amount of a silanol condensation catalyst to cure said composition upon exposure to moisture.
