Alternative Plasticizers As Emerging Global Environmental and Health

(1) Phthalate plasticizers have been regarded as hazardous compounds due to numerous reports based on its toxicological effects, including bioaccumulation potential, endocrine disruption, carcinogenicity, and developmental defects. (1?4) These findings resulted in global regulation measures and control of typical phthalate plasticizers (5?7) and...

Synthesis and Properties of Isosorbide-Based Eco-friendly Plasticizers

In this study, isosorbide-based eco-friendly and effective plasticizers were synthesized and characterized. Isosorbide esterification was conducted using fatty acids with different alkyl-chain lengths; the optimal degree of isosorbide esterification was obtained after 6 h reaction at 220 ¡ãC with a short alkyl-chain fatty acid in the presence of the catalyst Ti(OBu)4. Isosorbide-based

Free-radical polymerization of 2-hydroxyethyl methacrylate (HEMA

Introduction Nowadays, polymer chemists make great efforts to fine-tune the molecular weight (M n) and molecular weight distribution (dispersity, ?) of macromolecules as the key parameters that have a significant impact on the thermal rheological and morphological properties of the polymer materials. 1,2 At this point, it can be noted that over the last decades, the major focus was on the

Designed from Recycled: Turning Polyethylene Waste to Covalently

High-density polyethylene (HDPE) waste was successfully feedstock recycled, and the obtained chemicals were utilized for synthesis of plasticizers for polylactide (PLA). First, an effective route to recycle HDPE through a microwave-assisted hydrothermal process was established. This process led to selective degradation of HDPE to a few well-defined chemicals, namely, succinic, glutaric, and
