MOIST-CURED POLYMER FOR FLEXIBLE CABLES Russian patent published in 2022 - IPC C08L23/08 H01B3/44 H01B9/00 

FIELD: polymers.

SUBSTANCE: invention relates to an application of a polyethylene composition for improving adhesion between a cable layer containing the polyethylene composition and a polyurethane resin. Polyethylene composition contains one or multiple ethylene copolymers and a silanol condensation catalyst in the amount of 0.0001 to 5 wt.% of the total amount of the polyethylene composition. The ethylene copolymer constitutes a terpolymer containing monomer units with polar groups and monomer units with hydrolysable silane groups. Monomer units with polar groups are contained in an amount of more than 5 mol.% of the total amount of the polyethylene composition.

EFFECT: creation of a polyethylene composition as a cable layer, which can be cured or crosslinked under environmental conditions and does not require additional crosslinking, e.g., in vulcanisation tunnels.
