ADDUCTS OF LEVULINIC DERIVATIVES WITH EPOXIDATED FATTY ACID ESTERS AND USE THEREOF Russian patent published in 2011 - IPC C07D317/30 C07D307/16 C08K5/10 C08K5/101 C08K5/1535 C08K5/1565 

FIELD: chemistry.

SUBSTANCE: invention relates to compounds of formula , where R¹ denotes C₁-C₁₀ straight or branched alkyl or alkoxyalkyl; one of A or B denotes hydrogen and another denotes C₁-C₁₀ straight or branched alkoxycarbonyl group; "n" and "m" independently denote integers from 0 to 20. The disclosed compounds are suitable as plasticisers for polyvinyl chloride, poly-(3-hydroxyalkanoate) and polysaccharide. The invention also describes methods of obtaining said compounds through a reaction between derivatives of epoxidated fatty acid esters and levulinic acid esters. The present invention also relates to mono-, di- and tri-ketals which are adducts formed from reaction of alkyl esters of levulinate and epoxidated unsaturated fatty acid esters derived from vegetable oils.

EFFECT: improved properties of compounds.
