“…115 Other than fatty acids, linseed oil has been used as a carbon source for the production of PHAs. 117 UV-irradiation of these PHAs accelerated and enhanced the crosslinking reaction, resulting in an increase in the glass transition temperature of the polymers obtained from -51 • C to -32 • C.…”

Biobased polymers have seen their attractiveness increase in recent decades thanks to the significant development of biorefineries to allow access to a wide variety of biobased building blocks. Polyesters are one of the best examples of the development of biobased polymers because most of them now have their monomers produced from renewable resources and are biodegradable. Currently, these polyesters are mainly produced by using traditional chemical catalysts and harsh conditions, but recently greener pathways with nontoxic enzymes as biocatalysts and mild conditions have shown great potential. Bacterial polyesters, such as poly(hydroxyalkanoate)s (PHA), are the best example of the biotic production of high molar mass polymers. PHAs display a wide variety of macromolecular architectures, which allow a large range of applications. The present contribution aims to provide an overview of recent progress in studies on biobased polyesters, especially those made from short building blocks, synthesized through step-growth polymerization. In addition, some important technical aspects of their syntheses through biotic or abiotic pathways have been detailed.

“…Among the different classes of PHAs, middle‐chain‐length polyhydroxyalkanoates ( mcl ‐PHAs), in which the side group contains between 6 and 14 carbons, are of especial interest for adhesive and coating technology because they exhibit elastomeric and thermoplastic properties with a low crystallinity, low melting point, low T g (typical values comprised between −50 and −60°C), and high tack . Several studies have demonstrated the possibility of efficiently crosslinking mcl ‐PHA with γ rays, UV‐based processes, peroxide mediated reactions, free‐radical chemistry, and electron‐beam‐assisted processes and have, thus, improved their cohesive properties in view of PSA applications.…”

In this review, we provide a bird's eye view of recent developments in the field of pressure-sensitive adhesives (PSAs) derived from renewable monomeric building blocks. This emerging research field has been driven by increasing sustainability requirements in the adhesive industry and bridges the gap existing between highly optimized petroleum-based synthetic PSA systems, which display superior performance but lack biobased content, and historical PSAs derived from naturally occurring biopolymers (e.g., starch and natural rubber), which provide more environmentally friendly bonding solutions but have inherent technical limitations that prevent their more widespread implementation in today's technically demanding applications. We critically reviewed a representative (and exhaustive) survey of recent synthetic approaches to the development of biobased PSAs from the academic (articles) and industrial (patents) literature categorized in two families: chain-growth and step-growth polymerization routes. Finally, we draw a parallel between renewable synthetic PSAs and nature's selfadhesive glues, highlighting how the synergy between green chemistry and biomimetic concepts could inspire the emergence of a new generation of smart, synthetic, biobased PSAs with differentiated properties that approach the ones that are found in the natural world and with a wide spectrum of potential applications in the industrial and medical sectors.
