Sustainable Synthesis of Polyurethane Using Hydroxyl‐Terminated Polybutadiene (HTPB) Derived From the Degradation of Butadiene Rubber with Fatty Alcohol

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 11, November 2025.
This study proposes a synthesis route for polyurethanes (PUs) derived from bio‐based polyols. The polyols were obtained through metathesis depolymerization of butadiene rubber using fatty alcohol (a castor oil derivative) as a chain transfer agent to produce hydroxyl‐terminated polybutadiene (HTPB).

Mechanical Characteristics of Green Composites of Short Kenaf Bast Fiber Reinforced in Cardanol

open access: yesAdvances in Materials Science and Engineering, 2019
In this experiment, thermoset cardanol resin was reinforced with short kenaf bast fibers to produce 100% green composites. Different fiber loadings based on weight ratios (0%, 30%, 40%, 50%, and 60%) were fabricated by the hand layup method followed by ...

Epoxidized soybean oil: A sustainable solution to polyvinyl chloride recycling challenges

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 6, Page 1328-1342, November 2025.
Recycling process and characterization of polyvinyl chloride. Abstract Recycling process of polyvinyl chloride (PVC), a widely used plastic, is important in order to reduce its harmful environmental impacts and contribute to the circular economy. Thermal degradation of PVC during mechanical recycling significantly reduces its final properties and ...

Exploring Acrylic Acid as an Oxirane Nucleophile: Direct Access to Poly(β‐Hydroxy Acrylates)

open access: yesChemSusChem, Volume 18, Issue 18, September 23, 2025.
Within, we present a scalable, solvent‐free route to β‐hydroxy acrylate monomers using acrylic acid (AA) as a nucleophile with various oxiranes. Once polymerized, the resulting polymers are optically transparent, thermally stable, and range from brittle to ductile. This straightforward method underscores AA's potential in sustainable, bio‐based polymer
