Patent ID: 6864323

Claim:
A composition comprising (i) at least one silicon-containing compound; (ii) at least one peroxidic free-radical initiator; and (iii) at least one conjugated hydrocarbon comprising a mono- or polyunsaturated hydrocarbon chain and at least one aromatic hydrocarbon group, and/or at least one organofunctional silane of formula I: R—X n —C(R)═C(R)—C(R)═C(R)—X n —Si(R 1 ) m (OR 2 ) (3-m) (I), where the groups R are identical or different, and R is a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms, an aryl group or an aralkyl group, R 1 is a linear or branched alkyl group having from 1 to 4 carbon atoms, R 2 is a linear, branched, or cyclic alkyl group having from 1 to 8 carbon atoms, the X groups are identical or different, and X is —CH 2 —, —(CH 2 ) 2 —, —(CH 2 ) 3 —, —O(O)C(CH 2 ) 3 — or —C(O)O—(CH 2 ) 3 —, n is 0 or 1, and m is 0, 1, 2 or 3, and wherein the monounsaturated hydrocarbon chain of the conjugated hydrocarbon contains four or more carbon atoms.
