FIELD: chemistry.SUBSTANCE: group of inventions relates to a plasticising composition. Described is a plasticizing composition for a thermoplastic polymer selected from polyvinyl chloride (PVC), polyvinyl butyral (PVB), homopolymers and copolymers of vinyl acetate, homopolymers and copolymers of styrene, polyacrylates, thermoplastic polyurethanes (TPU) and polysulphides, containing: a) one or more compounds of general formula (I):in which X in each case denotes a straight alkylene group with 2-5 carbon atoms, Y in each case denotes a straight or branched alkylene group with 2-5, and is integer from 5 to 40, and R1denotes methyl, both denote ethyl, both denote n-propyl, both denote isopropyl, both denote n-butyl , both denote isobutyl or both denote n-pentyl, where the Y groups found in the compounds (I) can be identical or can differ from each other, and wherein if the compounds (I) contain more than one X group, the latter can be identical or can differ from each other, and b) one or more compounds of general formula (II):in which R2and R3are independently selected from branched and unbranched alkyl radicals with 8-11 carbon atoms, wherein content of the compound of general formula (I) in the plasticising composition is from 50 to 90 wt % and the content of the compound of general formula (II) in the plasticizing composition is from 10 to 50 wt %, in terms of total amount of compounds (I) and (II) in plasticising composition. Also disclosed are molding compound, use of plasticising composition, use of molding compound.EFFECT: high resistance of plasticisers to extraction, primarily extraction with petrol, oils and fats, as well as resistance to ultraviolet and volatility.13 cl, 3 tbl, 5 ex, 1 dwg Группа изобретений относится к пластифицирующей композиции.
