FIELD: chemistry. n SUBSTANCE: invention relates to processing plastic, particularly polyvinyl chloride-based polymer compositions, which are used in various industries, including for making insulation and sheaths of wires and cables. The composition contains 100 pts.wt polyvinyl chloride, 40-80 pts.wt plasticiser, 3-15 pts.wt heat stabiliser and 0.1-8.0 pts.wt filler, which is chemically deposited calcium carbonate with surface treatment with fatty acids with particle size of 15-70 nm. n EFFECT: introduction of said filler into the polyvinyl chloride-based composition reduces viscosity of the molten composition and increases frost-resistance thereof while preserving physical and mechanical properties. n 1 tbl, 25 ex |
