Preparation and Performance of Bio-Based Polyol Ester
Poly(vinyl chloride) (PVC), as one of the most widely used polymer materials, has been used to prepare various of products such as toys, food packing, wire and cable, optical fiber skin, shoes, ornaments, building decorations and so on, because it has the characteristic of low cost, high mechanical performance and excellent chemical resistance [1,2,3].
- What is plasticized polyvinyl chloride (PVC)?
- Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing.
- Can plasticizer improve the plasticity of polyvinyl chloride (PVC)?
- Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
- Is there a bio-based plasticizer for poly (vinyl chloride)?
- Feng G, Hu L, Ma Y, Jia P, Hu Y, Zhang M, Liu C, Zhou Y (2018) An efficient bio-based plasticizer for poly (vinyl chloride) from waste cooking oil and citric acid: synthesis and evaluation in PVC films.
- How are polyvinyl chloride (PVC) films prepared?
- The polyvinyl chloride (PVC) films (a/PVC, b/PVC and c/PVC) were prepared using a, b and c as bio-base plasticizers. The epoxidation and ring opening reactions were mainly investigated through GC-MS analysis. The structures of bio-base plasticizers (a, b and c) were confirmed by Fourier transform infrared spectroscopy (FT-IR), 1 H NMR and 13 C NMR.
- Does mixing plasticizers affect the thermal stability of PVC?
- The thermogravimetric test showed that the mixing of plasticizers will not negatively affect the thermal stability of PVC. Starting from the renewable green chemical levulinic acid, Sinisi et al. synthesized five asymmetric ketal-diester plasticizers. The schematic representation of the synthetic route has been showed in Scheme 19.
- What are bio-based PVC plasticizers?
- Many bio-based PVC plasticizers, such as vegetable oil-based plasticizers, cardanol-based plasticizers, lactic acid-based plasticizers, waste cooking oil-based plasticizers, polyester plasticizers, hyperbranched plasticizers and so on, have been extensively studied.
