FIELD: chemistry.
SUBSTANCE: invention relates to foamed polymer compositions containing peroxide-modified linear low-density polyethylene, which is a product of reaction of peroxide and linear low-density polyethylene, and a foaming agent. Low-density linear polyethylene modified with peroxide is thermoplastic. Also disclosed are a method of producing such polymer compositions and a cable insulated with a polymer coating containing said polymer composition. Foamed polymer compositions are suitable for use in various articles, particularly in conductor and cable industry.
EFFECT: polymer composition obtained using peroxide-modified linear low-density polyethylene is more effective in improving retention of elongation compared to other polyolefins.
