Oxime-Based and Catalyst-Free Dynamic Covalent Polyurethanes

TL;DR: A new class of the PU-like dynamic covalent polymers, poly(oxime-urethanes) (POUs), which are prepared from the uncatalyzed polyaddition of multifunctional oximes and hexamethylene diisocyanate at ambient temperature are reported, showing efficient catalyst-free healable/recyclable properties.
Journal ArticleDOI

Lignin-Based Polyurethanes: Opportunities for Bio-Based Foams, Elastomers, Coatings and Adhesives

TL;DR: The potential of incorporation of lignins into polyurethane products that include rigid and flexible foams, adhesives, coatings, and elastomers, and challenges in incorporating lignin in polyurehane formulations are discussed.
Journal ArticleDOI

Bio-Based Thermosetting Resins for Future Generation: A Review

TL;DR: In this paper, a review of agro-based polymer products derived from cardanol, itaconic acid, tannin, sugar (isosorbide), and vegetable oils is presented.
