SEMICONDUCTOR POLYMER COMPOSITION Russian patent published in 2024 - IPC C08L31/04 C08K3/04 H01B1/12 H01B9/00 

FIELD: polymer industry.

SUBSTANCE: invention relates to a semiconductor polymer composition. Disclosed is a semiconductor polymer composition containing, in wt.%: (a) from 30 to 73 of a base polymer, which is an ethylene-vinyl acetate copolymer, relative to the total weight of the semiconductor polymer composition, where the ethylene vinyl acetate copolymer has a vinyl acetate content of 3 to 22 wt.% relative to the total weight of the copolymer, (b) 25 to 60 carbon black, (c) 1 to 10 ethylene vinyl acetate wax and (d) at least 0.1 acid scavenger; article, which is a cable, a power cable or a layer in a multilayer cable and containing the disclosed semiconductor polymer composition, method of producing the disclosed semiconductor polymer composition and a method of producing the disclosed cable.

EFFECT: improved interaction between the compounding equipment and the disclosed composition, which reduces the energy consumption of the compounding equipment during the compounding process, and obtained composition must have sufficient smoothness to be considered suitable for use in power cables.
