PLASTICISER COMPOSITION FOR POLYVINYL CHLORIDE, PLASTISOL AND PLASTIFICATE ON ITS BASIS Russian patent published in 2017 - IPC C08K5/10 C08L27/06 

FIELD: chemistry.

SUBSTANCE: plasticiser composition for polymers based on vinyl chloride, including a mixture of compounds of the general formula , where R₁, identical or different, is selected from linear or branched C₈-C₂₀alkyl, R₂ is selected from linear or branched C₁-C₆alkyl, wherein alkyl may be optionally substituted with one or more substituents selected from halogen, hydroxyl, C₁-C₆alkoxy, halogen-C₁-C₆-alkyl, C₅-C₁₀aryl or C₅-C₁₀heteroaryl with 1 to 3 heteroatoms selected from N, O and S, in which the content of compound II is from more than 2 to 10 wt % of the total weight of the compound mixture I and II. A method of producing a polymer product is also described, comprising the step of mixing the above composition with a vinyl chloride-based polymer and optionally with auxiliary additives. Plastisol and a plasticate produced by the above method are described. A PVC article produced using the above plastisol or plasticate is described. A composition for producing a polymeric product comprising: A) a plasticiser composition comprising a mixture of compounds of the general formula , where R₁, identical or different, is selected from linear or branched C₈-C₂₀alkyl, R₂ is selected from linear or branched C₁-C₆alkyl, where alkyl may be optionally substituted with one or more substituents selected from halogen, hydroxyl, C₁-C₆alkoxy, halogen-C₁-C₆-alkyl, C₅-C₁₀aryl or C₅-C₁₀heteroaryl with 1 to 3 heteroatoms selected from N, O and S, wherein the content of compound II is 2 to 10 wt % of the total weight of the compound mixture I and II, b) vinyl chloride-based polymer.

EFFECT: increasing the speed of penetration of the plasticiser into PVC particles, with the improvement of the physico-mechanical characteristics of the finished products.
