FIELD: polymer materials.
SUBSTANCE: invention relates to compositions of polymer materials, which can be used to mold cutouts, fibers, tubes, films, and insulating coating on electric cable. Thermoplastic polymer material comprises polyolefin and additive for improving extrusion processing in amounts from 0.001 to 10 wt parts per 100 wt parts material. Additive is block copolymer based on diisocyanates with softening temperature below thermoplastic molding temperature.
EFFECT: improved appearance and mechanic characteristics and reduced price of manufactured products.
