Abstract
Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, a phenolic antioxidant, and an ester-functionalized thioether. Such crosslinkable polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.
Claims15
A silane-crosslinkable polymeric composition, comprising:
- a polyolefin having hydrolyzable silane groups;
- an acidic silanol condensation catalyst;
- a phenolic antioxidant having no tertiary-alkyl-substituted aryl or phenolic groups;
- an ester-functionalized thioether;
- and
- 4,4′-di(dimethylbenzyl)diphenylamine.
3 more elements
A process for preparing a silane-crosslinkable polymeric composition, said process comprising:
- combining a polyolefin having hydrolyzable silane groups;
- an acidic silanol condensation catalyst;
- a phenolic antioxidant having no tertiary-alkyl-substituted aryl or phenolic groups;
- an ester-functionalized thioether;
- and 4,4′-di(dimethylbenzyl)diphenylamine to thereby form said silane-crosslinkable polymeric composition,
- wherein said acidic silanol condensation catalyst, said phenolic antioxidant, and said ester-functionalized thioether are present in the form of a masterbatch when combined with said polyolefin having hydrolyzable silane groups,
- wherein said masterbatch further includes at least one matrix resin.
