  • Patent number: 11421098
    Abstract: The present invention relates to the use of a depleted epoxidized fatty acid ester mixture as plasticizer in a halogenated resin composition, said ester being obtainable by a process comprising epoxidation of a vegetable oil, transesterification of the epoxidized vegetable oil, short path distillation of the trans-esterified epoxidized vegetable oil and selection of the non-vaporized fraction of the preceding process step. The depleted ester mixture is suitable for being incorporated in halogenated resin compositions at a ratio exceeding 40 phr, without causing rheological or other problems to occur under practical industrial applications for the plasticized resin composition.

  • Patent number: 10858611
    Abstract: The present invention relates to a process for preparing two mixtures of epoxidized fatty acid esters, comprising in the order given a transesterification of an epoxidized vegetable oil, followed by a reduction of the volatile saturated non-epoxidized fraction by short path distillation of the transesterified epoxidized vegetable oil, followed by a selection on the one hand of the non-vaporized fraction (residue) of the previous process step as the first mixture of epoxidized fatty acid esters and a selection on the other hand of the vaporized fraction (distillate) as the second mixture of epoxidized fatty acid esters. The first mixture is in particular suitable as plasticizer in halogenated polymers, the second mixture being particularly suitable as plasticizer in non-halogenated polymers.

  • Patent number: 9822238
    Abstract: The present invention refers to a composition comprising tetrahydrofurfuryl and alkoxylated alkyl esters and their use as plasticizers in biodegradable resins, more in particular, in a biodegradable aliphatic polyester resin comprising polylactic acid. In a preferred embodiment the composition comprises a tetrahydrofurfuryl butyldiglycolate ester. The invention also refers to a biodegradable resin composition, more in particular, comprising homo- or co-polymers of polylactic acid and comprising such compositions.

  • Patent number: 9359487
    Abstract: The present invention relates to plasticizers for use in a thermoplastic polymer. The plasticizers according to the invention comprise a succinate mixed ester of benzyl on the one part and branched nonyl or decyl on the other part. According to a preferred embodiment the molar amount of mixed ester in the plasticizer amounts to at least 30%. The invention also relates to plastisoles comprising such plasticizers.
