Summary: In this study, eco-friendly and effective plasticizers based on isosorbide were synthesized and characterized. The alkyl-chain length of the plasticizer was found to affect the properties of PVC sheets, where increasing the alkyl-chain length improved the strength and modulus of the PVC sheets but reduced their elongation. Epoxidation of the plasticizer enhanced its plasticizing properties, and the synthesized plasticizers exhibited better thermal stability compared to a commercial plasticizer.

Summary: This study investigated the effects of silane treatment on the properties of fly ash and recycled PVC composite materials, revealing significant enhancements in thermal stability, tensile strength, and young's modulus, as well as improvements in the distribution and water absorption properties of the composites. These findings suggest that silane-treated fly ash can be effectively utilized in composite materials with recycled PVC for enhanced performance.

Summary: Two castor oil acid esters containing a ketal or ketone group were prepared as alternative plasticizers for PVC, showing excellent plasticizing properties and improved thermal stability and migration resistance of the PVC blends. Introducing ketal groups into plasticizer may be an effective strategy for enhancing plasticizing efficiency.

Summary: Polyvinyl chloride (PVC), an important plastic derived from petroleum, has been widely used in daily life due to its superior properties. However, the unmanaged increase of PVC in the natural world has led to serious environmental issues. In order to achieve sustainable development, PVC waste can be recycled, reused, or converted into other high-value chemicals. This review provides an overview of mechanical and chemical approaches to recycling PVC waste, as well as the challenges and future perspectives.

Summary: The glass transition dynamics of polymers play a crucial role in determining their properties. Pyrene-labeled and pyrene-doped flexible PVC plasticized by ultra-small branched star poly(epsilon-caprolactone) were prepared to observe changes in fluorescence intensities with temperature. The study revealed limited movement of the labeled pyrene moieties along the PVC chains due to cooperative reptation motion, and showed that an increase in USB-SPCL content in flexible PVC can decrease fluorescence intensity reduction degrees while also potentially leading to an increase under certain conditions.

Summary: In order to achieve wider applications of soft PVC, a series of three-arm star copolymers with a hard PLA-rich core and a soft PCL-rich shell (S3-PLA-PCL) were prepared as plasticizers. The monomer ratio, average polymerization degree, and type of LA were optimized to achieve the best mechanical performance of soft PVCs. The S3-PLA-PCL plasticized PVC exhibited higher modulus, strength, and toughness compared to other traditional plasticizers, highlighting the importance of the star topology and hard core in strengthening soft PVCs. Additionally, the S3-PLA-PCL plasticized PVC showed good migration resistance and transparency, making it a high-performance, green polymeric plasticizer for PVC plastics.

Summary: The study investigated the thermal stability of PVC with 1 wt % of spherical porous nanosilica prepared by roll milling at various processing times. The addition of porous nanosilica was found to improve thermal stability by absorbing HCl gas produced during dehydrochlorination reaction, resulting in minor color changes and lower evolution of hydrogen chloride gas. The results showed that TGA measurements were not sensitive enough to detect PVC degradation at processing conditions below 220 degrees C.

Summary: Poly(vinyl chloride) (PVC) is a widely used plastic with brittleness and inflexibility. This study successfully synthesized green plasticizers CDOL-L and CDOL-LKE, and developed highly stretchable and stable PVC-based plastics. The new plasticizers showed superior stability in thermal, mechanical, and migration properties compared to traditional ones, and demonstrated potential for substituting traditional plasticizers.

Summary: In this study, internal plasticization of PVC was achieved in one-step by grafting different ratios of random n-butyl acrylate and 2-2-(2-ethoxyethoxy)ethyl acrylate copolymers from defect sites on the PVC chain using copper-mediated atom transfer radical polymerization. The resulting PVC graft copolymers exhibited good compatibility with PVC, improved plasticization efficiency, and enhanced thermal stability compared to unmodified PVC. Increasing the reaction scale could produce consistent and reproducible results, indicating potential industrial applicability.

Summary: This study focused on the design and synthesis of a series of bio-based diester plasticizers with different alkyl chain asymmetry, using renewable HFCA as the raw material. The chemical structures of the plasticizers were characterized, and it was found that increasing the alkyl chain asymmetry while keeping the molecular weight unchanged could enhance plasticizing efficiency without compromising other properties. This research provided a new approach for optimizing the overall properties of asymmetric diester plasticizers.

Summary: Plasticizers synthesized from renewable oleic acid outperformed traditional DOA plasticizers in terms of performance, exhibiting excellent migration resistance and flexibility in cold environments. These plasticizers have the potential to replace toxic DOP and poorly stable DOA, providing an effective and green solution to the harm of plastic products to human health and the environment. Additionally, they expand the application of PVC in cold environments, contributing to the sustainability of the often criticized PVC industry.

Summary: The utilization of biobased resources for high-performance plasticizers is a novel approach, but the combustibility of PVC products with high content plasticizers is often overlooked. A novel biobased flame-retardant plasticizer (VA8-P) has been synthesized, which exhibits exceptional comprehensive properties in PVC, including lower glass transition temperature, higher low temperature resistance, and higher elongation at break.
