Development of a Highly Efficient Environmentally Friendly Plasticizer

Abstract

The purpose of this work is the synthesis of adipic acid ester and the study of the possibility of its use as a PVC plasticizer. The resulting butyl phenoxyethyl adipate was characterized by Fourier-transform infrared spectrometry, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The compatibility, effectiveness and plasticizing effect of butyl phenoxyethyl adipate in comparison with dioctylphthalate (DOP) were determined. The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition temperature was 132.2 °C in relation to pure PVC and 7.7 °C in comparison to compounds based on DOP. An increase in the fluidity of the melt of polyvinyl chloride (PVC) compounds in the temperature range of 160–205 °C by 19–50% confirms a decrease in the energy intensity of the processes of manufacturing and the processing of polymer materials containing a new additive.

A highly stable bio-based plasticizer constructed from renewable acids for plasticizing and enhancing the optical properties of poly(vinyl chloride)

“…Three samples of each plasticized PVC film were prepared to obtain an average value. The elastic modulus could be calculated by eqn (1). The hardness of the PVC sample was detected using a Shore Hardness Tester according to ISO 868:2003.…”

“…Polyvinyl chloride (PVC) is one of the most widely used polymers in the world today, [1][2][3] and is used in various important fields such as food packaging, medical equipment, the automobile industry, and children's toys. [4][5][6] Its widespread use is not only due to its low price, but also the presence of plasticizers.…”

“…By pre-considering the influence of plasticizer structure on the properties of polymer materials, researchers carried out planned group modification of biomass chemical raw materials to obtain various new high-efficiency bio-based plasticizers. 1,19 These studies promote the gradual replacement of traditional petroleum-based plasticizers with environmentally friendly plasticizers.…”
