From Petrochemical Polyurethanes to Biobased Polyhydroxyurethanes

Application of high-strength biodegradable polyurethanes containing different ratios of biobased isomannide and poly (ϵ-caprolactone) diol

Biodegradable-biocompatible polyurethanes were prepared with fixed hexamethylene diisocyanate and varying ratios of isomannide and poly(ϵ-caprolactone) diol using a simple one-step polymerization without a catalyst. The polyurethane structures were confirmed by 1H-nuclear magnetic resonance, Fourier transform infrared spectroscopy, and gel permeation chromatography. The glass transition tempera...

A novel 2,5-furandicarboxylic acid-based bis(cyclic carbonate) for the synthesis of biobased non-isocyanate polyurethanes

This paper describes the synthesis of a new biobased bis(cyclic carbonate) derived from 2,5furandicarboxylic acid (FDCA) with the incorporation of CO2. The bis(cyclic carbonate) was then used to synthesize non-isocyanate polyurethanes (NIPUs) via polyaddition reactions with a series of diamines. The chemical structures of the bis(cyclic carbonate) and the NIPUs were characterized by Fourier tra...

Biobased Polyurethane from Palm Kernel Oil-Based Polyol

Biocatalysis for Biobased Chemicals

The design and development of greener processes that are safe and friendly is an irreversible trend that is driven by sustainable and economic issues. The use of Biocatalysis as part of a manufacturing process fits well in this trend as enzymes are themselves biodegradable, require mild conditions to work and are highly specific and well suited to carry out complex reactions in a simple way. Th...

Biobased performance bioplastic: Mirel.

Each year over 140 million tons of petroleum-based polymers are produced worldwide and used in the production of such plasticsaspolyethylene, polystyrene, polyvinyl chloride, polyurethane, and others. Mostly using oil, coal, and natural gas as raw materials for their manufacturing, these plastics are common in every facet of our lives from the pharmaceutical industry to household use. Approxima...
