MOISTURE CROSSLINKABLE POLYMERIC COMPOSITION CONTAINING SPECIAL ANTIOXIDANTS

摘要

The present invention is a moisture-crosslinkable polymeric composition comprising (a) a silane-functionalized olefinic polymer, (b) an acidic silan ol condensation catalyst, and (c) an antioxidant, not having a tertiary alkyl- substituted aryl or phenolic group, wherein the polymeric composition does n ot generate a high amount of foul-smelling or combustible gases. Alternatively, the antioxidant is substantially free of substituents vulnerable to dealkylation in the presence of the acidic silanol condensation catalyst and at conventional processing conditions. The invention also includes methods f or preparing the moisture-crosslinkable polymeric composition. The moisture- crosslinkable polymeric compositions can be used as a coating and applied ov er a wire or a cable.
