COMPOSITIONS CONTAINING LDPE, POLYPROPYLENE AND FUNCTIONALISED POLYOLEFINS Russian patent published in 2024 - IPC C08L23/08 C08L23/12 C08L23/14 C08K5/00 H01B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a polymer composition suitable for making cables, which contains low-density polyethylene (LDPE), polypropylene and two polyolefins: one containing epoxy groups and the other containing carboxylic acid groups or precursors thereof, and to methods of producing a composition and a cable; also described are cables containing the disclosed compositions.

EFFECT: providing a composition with improved thermomechanical characteristics due to reduced phase separation in polypropylene-LDPE mixtures when used in mixtures of polyolefin containing epoxy groups and polyolefin containing carboxylic acid groups and/or precursors thereof.
