Lactide-derived ester oligomers for highly compatible poly
First, hydroxyl-ended lactide oligomers were precisely prepared with target molar mass values of 330–430 g mol 1 by controlled bulk ring opening oligomerization using 1-, 2-, and 3-arm initiators. They were subsequently esterificated with acetic anhydride to produce acetyl-terminated lactide oligomers (ALO) with enhanced thermal stability.
Bioplasticizer - an overview | ScienceDirect Topics
In the mid-1970s, Hercules Chemical Company introduced two polyol ester plasticizers, Hercoflex 600 and Hercoflex 707. These plasticizers were prepared by the esterification of pentaerythritol and dipentaerythritol with a mixture of short-chain acids, predominately C6 acid.
Research progress of novel bio-based plasticizers and their
2,5-Dicarboxylic acid ester is derived from biomass resources, but has a structure similar to terephthalic acid ester. As a green chemical, it has the potential to replace petroleum-based plasticizers. Nguyen et al. used raw materials derived from marine biomass to synthesize furan-2,5- and furan-2,3-dicarboxylate as plasticizers for PVC. The
Chlorinated Ester Plasticizers - ResearchGate
Stabilized chlorinated esters (CEs), specifically those derived from esters of palm kernel, palm, and coconut oils, act as viable replacements for chlorinated paraffins (CPs) as secondary...
Synthesis and properties of a bio-based PVC plasticizer
The new plasticizer ALHD gave PVC products better toughness and strength; therefore, it can be used as either a primary or secondary plasticizer. Thermal stability and DSC analysis Thermal stability of the plasticizers and PVC specimens was researched using TGA and the obtained data are shown in Fig. 9 and Table 3.
- Are epoxidized cardanol ester stabilizers suitable for PVC films?
- In this work, two different epoxidized cardanol ester stabilizers were synthesized, and their structures were characterized. Moreover, their synergistic plasticizing and thermal stabilization effects on PVC were studied, and PVC films with excellent mechanical and thermal stability were prepared.
- Can biobased plasticizer be used as a heat stabilizer?
- The plasticizing effect of single biobased plasticizer is not good. Biobased plasticizer with synergistic effects is required. There exists the trade-off effect between the molecular weight and the compatibility. Epoxidized isosorbide ester can be used as a heat stabilizer. The authors declare that they have no conflict of interest.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Which plasticizer possesses a favorable plasticization effect on PVC?
- Among, Yao et al. synthesized an environmental-friendly plasticizer CEP originated from cardanol by click chemistry, the results showed that it possessed favorable plasticization effect and stabilization effect on PVC. Zhu et al. designed and synthesized a new type of VA-based plasticizer (VA4-Cn).
- Are organic heat stabilizers suitable for PVC?
- In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
- Can epoxidized isosorbide ester be used as a heat stabilizer?
- Epoxidized isosorbide ester can be used as a heat stabilizer. The authors declare that they have no conflict of interest. Abstract Plasticizers are widely used in poly (vinyl chloride) (PVC), polylactic acid (PLA), thermoplastic starch (TPS), and other modified powder materials to enhance the flowability, flexibility, ...
