Abstract

A mixture of isomeric dipentyl terephthalates, pentyl radicals of which are n-pentyl radicals to an extent of less than 60 mol %, characterized by a low viscosity which does not increase significantly even at temperatures below 40° C. Plastisols comprising these mixtures have a low plastisol viscosity which moreover increases only to a minor degree with time.
