FIELD: chemistry.

SUBSTANCE: group of inventions relates to silane cross-linkable polymer compositions. Disclosed is a silane cross-linkable polymer composition for insulating coatings, comprising: a polyolefin containing hydrolysable silane groups; acid catalyst of silanol condensation; thioether, functionalised with an ester; and a phenolic antioxidant having the following structure:

,

where X¹ and X² are independent sulfur-containing radicals, where R¹, R² and R³ independently represent hydrogen atoms or hydrocarbon radicals, optionally containing one or more heteroatoms. Coated conductor is also provided.

EFFECT: improved performance of article from silane crosslinkable polymer composition.
