Abstract

Tripentyl esters of trimellitic acid, especially mixtures of triisopentyl esters of trimellitic acid comprising isomeric pentyl radicals in which more than 5 mol % of the isomeric pentyl radicals incorporated in the ester mixture are branched, have good compatibility with PVC and PVC-containing polymers and simultaneously exhibit a lesser tendency to migrate.
