“…Ozonolysis, epoxidation, hydroformylation, transesterification, amidation and thiol-ene coupling are the most developed methods for the functionalization of double bonds for the synthesis of polyols using vegetable oils. 359 Dimers of diisocyanate, polyol, diamine, and dicyclocarbonate with cyclohexene ring can be produced via the dimerization of fatty acids, e.g., Diels Alder cycloaddition [4+2] of linoleic and linolenic acids at high temperature. 360 The pending aliphatic chains of these dimers can bring mobility to the final polymers.…”

“…These monomers can be derived from vegetable oils or lignocellulosic biomass. [15] Making bio-based precursors for isocyanate monomers is still a challenge, but some examples can be found in the literature. [16,17] At present, the main drawback of bio-derived polymers remains their higher price compared to petroleum-based ones.…”

Nitrogen-containing polymers are widely applied materials, including polyamides, polyurethanes, and polyureas as well as epoxy thermosets. Their indispensability and the urgent need to replace fossil-based polymers considering more sustainable alternatives lead to significant efforts in exploring renewable feedstock as potential new building blocks. Being obtained from non-edible plant parts and often occurring as waste products, terpenes represent a promising group of renewable compounds that are of possible interest in the synthesis of nitrogen-containing polymers. The structural diversity of terpenes in combination with the mechanical properties that nitrogen-containing moieties bring into polymers can give rise to novel biobased materials that outstand mechanical and thermal properties of conventional fossil-based counterparts. In this review, an overview of the use of terpene compounds in the synthesis of nitrogen-containing polymers is given, covering different approaches to make use of terpenes as a valuable pool of renewable monomers.

“…At present, the main kinds of waterborne polyols used to prepare 2K-WPU are waterborne acrylic polyol dispersion, waterborne polyurethane polyol dispersion and waterborne polyester polyol dispersion, most of which are synthesized from fossil resources. Replacing fossil resources with renewable biomass resources have been considered as one of the most promising renewable feedstocks to prepare green compounds with low environmental load [14][15]. Rosin is a characteristic forestry resource in China, with an annual output of about 400-thousand tons.…”

Due to the complex heterogeneous lm forming process of two-component waterborne polyurethane (2K-WPU), the crosslinking reaction rate of 2K-WPU cannot meet the demand of e cient application in coatings. In order to improve the crosslinking reaction rate of 2K-WPU, a waterborne polyol containing tertiary amine groups was synthesized from rosin based epoxy resin and secondary amine compound, and then autocatalytic 2K-WPU was prepared by crosslinking the rosin based waterborne amino polyol with polyisocyanate. The structure of the polyol from rosin based epoxy resin was characterized with Fourier infrared (FT-IR) and nuclear magnetic resonance (NMR). The crosslinking kinetics and the crosslinked product of the rosin based waterborne amino polyol were also compared with a commercial acrylic polyol. It was shown from the results that the crosslinking reaction rate of the rosin based waterborne amino polyol was faster than that of the commercial acrylic polyol, which indicated the tertiary amine groups chemically bonded in the rosin based polyols could autocatalyze the crosslinking reaction of 2K-WPUs with catalysts free. The lm of the rosin based waterborne amino polyol had excellent impact strength, adhesion, exibility, hardness, gloss, fullness and solvent resistance, showing a good application prospect in the eld of waterborne coatings.
