摘要
The present invention relates to a mixture comprising diesters of the formula (I) where R1 to R8H or alkyl group having from 1 to 6 carbon atoms, where the R1 to R8 radicals may be the same or different, which is characterized in that at least two different diesters I are present in the mixture, said diesters differing in the structure of at least one of the carboxylic acid radicals C8H17COO present, to a process for preparing diesters of an isosorbide derivative of the formula I, in which a hexahydric alcohol and/or a monoanhydro or dianhydro derivative of the alcohol is esterified with a mixture of at least two different carboxylic acids of the empirical formula C8H17COOH, and to the use of these mixtures in paints, inks or coatings, in plastisols, adhesives or adhesive components, in sealants, as plasticizers in polymers or polymer components, as solvents, as lubricant oil components and as assistants in metal processing, and also PVC compositions or plastisols comprising PVC and from 5 to 250 parts by mass of the mixture per 100 parts by mass of PVC.
