The present invention relates to one-part closure devices encompassing at least polyvinyl chloride and at least one plasticizer, in particular at least one substituted or unsubstituted cyclohexanedicarboxylic acid or a derivative thereof, to a process for producing a closure device of this type, and also to the use of a closure device of the invention as a closure for containers, in particular for wine bottles or other bottles.

Single piece closure device made of PVC

A process is described for preparing mixtures of diesters of phthalic acid with decanols and tridecanols by reacting phthalic acid or a reactive derivative of phthalic acid with a mixture made from at least one decanol and at least one tridecanol. Mixtures obtainable in this way are also described, as is their use as plasticizers for molding compositions, and also mixtures of isomeric tridecanols suitable for preparing the mixtures of diesters.
