Abstract
A curable sealant compound comprising: a polythiol; a cyclopolyene having a formula: where X is C1-5 aliphatic, Y is a C1-6 aliphatic, R2 is in each occurrence H, C1-C10 alkyl, C2-C10 alkenyl, Q—R3 where Q is O or S and R3 is C2-10 alkenyl, such that the cyclopolyene has non-conjugated carbon—carbon unsaturated bonds, and in formula (VII) there is one non-conjugated carbon—carbon unsaturated bond within the ring that is non-conjugated to other carbon—carbon unsaturated bonds; and an effective amount of a free radical catalyst.
