Abstract:
A crosslinkable polyolefin composition comprising an polyolefin modified with hydrolyzable alkoxysilane groups and a silanol crosslinking catalyst selected from the group consisting of:(i) an alkylated aryl disulfonic acid selected from the group consisting of and structure II â€ƒwherein each of R1 and R2 is the same or different and is a linear or branched alkyl group with 6 to 16 carbons, y is 0 to 3, z is 0 to 3 with the proviso that y+z is 1 to 4, n is 0 to 3, X is a divalent moiety selected from the group consisting of â€”C(R3)(R4)â€”, wherein each of R3 and R4 is H or independently a linear or branched alkyl group of 1-4 carbons and n is 1; â€”C(&boxH;O)â€”, wherein n is 1; â€”Oâ€” wherein n is 1; â€”Sâ€”, wherein n is 1 to 3; and â€”S(O)2â€”, wherein n is 1; and (ii) a derivative of (i) selected from the group consisting of the anhydrides, esters, epoxy blocked sulfonic acid esters, acetylates, and amine salts thereof which is hydrolyzable to the alkylated aryl disulfonic acid.
