Abstract In response to the health and environmental concerns associated with plasticizer dioctyl phthalate (DOP), this research explores utilization of methyl oleate (MO) derived from plant oil, 1,2,4‐Benzeneticarboxylic anhydride (TMA) isobutyric (IA) as a precursor for synthesizing hyperbranched polyester named IA‐MO‐TMA. This serves an alternative Polyvinyl chloride (PVC). The chemical structure IA‐MO‐TMA was thoroughly characterized using Fourier Transform Infrared Spectrometer (FTIR) nuclear magnetic resonance hydrogen spectra, its molecular weight assessed. PVC film, plasticized IA‐MO‐TMA, underwent comprehensive testing techniques such differential scanning calorimetry, electron microscopy, thermogravimetric analysis. Notably, glass transition temperature ( T g ) film exhibited significant reduction 75°C −6.7°C. demonstrated elongation at break 318.1%, tensile strength 19.2 MPa, plasticizing efficiency 109.9%. Moreover, use increased initial decomposition 235.6 264.1°C. Additionally, extraction rate in petroleum ether found be 35.6% lower than that DOP.

Integration of Biological Synthesis & Chemical Catalysis: Bio-based Plasticizer trans-Aconitates

Green Carbon, Год журнала: 2023, Номер 1(1), С. 20 - 32

Опубликована: Авг. 10, 2023

Plasticizers are essential to reduce processing difficulties and improve plastic properties. However, petroleum-based phthalate plasticizers, which mostly used at present, urgently require alternatives due their confirmed serious health risks. In this study, the green mass production of trans-aconitic acid was achieved via synthetic biotechnology microbial fermentation, further expanded multiple application scenarios using chemical esterification, resulting in trans-aconitate plasticizers that biosafe environmentally friendly have high plasticizing efficiency long-term stability. Different with various core structures alkyl chains were studied determine properties as polyvinyl chloride (PVC) tributyl (TBA) displayed best comprehensive performance up 1.24 efficiency. The possible PVC plasticization mechanism synergistic solvent, support, shielding effects discussed summarized. Tributyl has significant potential replace traditional general merchandise, food packaging, medicinal materials, other products, promoting development high-quality industry greener technology safer applications.

Design of Anti‐Migratory and Thermally Stable Bio‐Plasticizers for Polar Plastics Toward Superior Overall Performance

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Март 23, 2025

ABSTRACT Developing bio‐based plasticizers for polyvinyl chloride (PVC) that exhibit effective plasticizing performance, thermal stability, and migration resistance remains a significant challenge. In this work, two plasticizers, acetylated methyl oleate citrate (A‐MO‐CAE) n‐butyl (A‐NBO‐CAE), were synthesized by using fatty acid esters citric as raw materials compared with the commercial plasticizer bis(2‐ethyl)hexyl phthalate (DEHP). It was found PVC plasticized A‐MO‐CAE, shorter alkane chain, had better overall performance; alkyl chain of A‐MO‐CAE increases intermolecular distance PVC, ester group interacts which results in good effect. The Tg PVC/50A‐MO‐CAE 43.3°C; meanwhile, heat than PVC/50DEHP, did not oxidize turn black after aging 1 h at 180°C. elongation break (EB) 633.3%, higher PVC/50A‐NBO‐CAE (456.6%) PVC/50DEHP (429.2%). More importantly, weight loss volatility leaching tests much lower PVC/50DEHP. These indicate has potential to replace DEHP, providing straightforward practical way preparation plasticizers.
