Abstract:
A crosslinkable polyolefin composition comprising a polyolefin modified with hydrolyzable silane groups and a silanol crosslinking catalyst selected from the group consisting of:(i) an alkylated naphthalene monosulfonic acid substituted with 1-4 alkyl groups wherein each alkyl group is a linear or branched alkyl with 5-20 carbons with each alkyl group being the same or different, wherein the total number of carbons in the alkyl groups is in the range of 20 to 80 carbons; (ii) an arylalkyl sulfonic acid wherein the sulfonic acid is attached to the alkyl group, the aryl is phenyl or naphthyl and is substituted with 1-4 alkyl groups wherein each alkyl group is a linear or branched alkyl with 5-20 carbons with each alkyl group being the same or different, and wherein the total number of carbons in the alkyl groups is in the range of 12-80; (iii) a derivative of (i) or (ii) selected from the group consisting of an anhydride, an ester, an acetylate, an epoxy blocked ester and an amine salt thereof which is hydrolyzable to the corresponding alkyl group is a linear or branched alkyl with 10-18 carbons with each alkyl group being the same or different, wherein the total number of carbons in the alkyl groups is in the range of 20 to 70 carbons.
