  The present invention refers to a plasticiser, said plasticiser being an ester formed by reaction of a pentaerythritol and a monocarboxylic acid, having 4-5 carbon atoms. In a further aspect the present invention refers to the use of said plasticiser in blends and in a PVC resin. The plasticiser of the present invention is a non-phthalic plasticiser that has proven to have shorter fusion time and higher plasticising efficiency compared to commercial non-phthalic PVC plasticisers.

  本发明涉及一种增塑剂，该增塑剂是由戊四醇和一种具有4-5个碳原子的单羧酸反应形成的酯。在进一步的方面，本发明涉及在混合物和PVC树脂中使用该增塑剂。本发明的增塑剂是一种非邻苯二甲酸酯增塑剂，已被证明与商业非邻苯二甲酸酯PVC增塑剂相比具有更短的熔融时间和更高的增塑效率。
