Biobased Amines: From Synthesis to Polymers; Present and Future

Abstract

Amines are key intermediates in the chemical industry due to their nucleophilic characteristic which confers a high reactivity to them. Thus, they are key monomers for the synthesis of polyamides, polyureas, polyepoxydes, which are all of growing interest in automotive, aerospace, building, or health applications. Despite a growing interest for biobased monomers and polymers, and particularly polyamides, it should be noticed that very few natural amines are available. Actually, there is only chitosan and poly(lysine). In this review we present both fundamental and applied research on the synthesis of biobased primary and secondary amines with current available biobased resources. Their use is described as a building block for material chemistry. Hence, we first recall some background on the synthesis of amines, including the reactivity of amines. Second we focus on the synthesis of biobased amines from all sorts of biomass, from carbohydrate, terpenes, or oleochemical sources. Third, because they need optimization and technological developments, we discuss some examples of their use for the creation of biobased polymers. We conclude with the future of the synthesis of biobased amines and their use in different applications.

Ring‐Opening Polymerization of a New Diester Cyclic Dimer of Mandelic and Glycolic Acid: An Efficient Synthesis Method for Derivatives of Amorphous Polyglycolide with High Tg

“…The main application fields of polyglycolide (PGL) and related copolymers have been medical and pharmaceutical, utilizing its biocompatibility, bioabsorbability, and biodegradability . More recently, due to increasingly important needs for a more sustainable industry, PGL has also been featured to explore more general applications for a larger plastic market such as commodities, stationery supplies, containers, etc., as a family member of biobased polymers, with developing production processes of biobased glycolic acid . Not only the sustainable aspect of PGL as a biobased polymer but also the promising functionalities of PGL are important features.…”
