FIELD: chemistry. ^ SUBSTANCE: invention relates to chemical and food industry, particularly to production of biodegradable plastic materials and can be used to make moulded or film articles for various purposes, including food purposes. The polymer composition for moulding biodegradable articles from molten mass contains polyolefins, biodegradable filler - starch and a process additive, which is a protein phosphatide concentrate (or fuzz) - a by-product of production of unrefined sunflower or rapeseed oil. ^ EFFECT: obtaining a polymer composition which can decompose under the effect of environmental factors and can be digested by microorganisms, having good biodegradation properties, and also capable of reducing the cost of the product and power consumption during production. ^ 2 dwg, 1 tbl, 3 ex |
