“…Similarly, diacide from self-metathesis of 10undecenoic acid has been reacted with 1,6-hexamethylene diamine to obtain a biobased polyamide [17]. Polyamides for hot-melt adhesive applications have been also synthesized from fatty acid dimers [18][19][20][21]. Recently, linear C19 and C23 long-chain a,v-diacid compounds have been prepared by isomerising alkoxy-carbonylation of either oleic and erucic acids, or triglycerides following hydrolysis [22][23][24].…”

The existence of entirely biobased AA-BB polyamides is very limited because of the low availability of biosourced diamines. In this work, saturated and unsaturated diamines, with dangling hexyl chain, were successfully synthesized from methyl ricinoleate. These new monomers were reacted with several diacids to prepare novel partially to totally biobased AA-BB polyamides. Linear polyamide analogues were also prepared from commercial monomers. The physico-chemical properties of the obtained polymers were assessed by DSC and TGA analysis. An auto-plasticizing effect owing to the dangling chains was evidenced. The new branched monomers and polymers are expected to be used when modification of the properties of existing polyamides are required.Practical applications: The new branched monomers and polymers are expected to be used as green and renewable plasticizers for modification of the properties of existing polyamides. Furthermore, the presence of the carbon-carbon double bonds in the main chains would be beneficial to perform polyamide chemical modifications at the molten state or to achieve cross-linking reactions suitable for coating applications.

“…The same trend is observed with uniaxial tensile testing (Table ). Regarding 50/50 biocomposites, the addition of CF limits the drop in the storage modulus which results in a higher thermal‐mechanical stability of the material at high temperature . Chemical modifications, particularly with P 2000, lead to higher mechanical properties (after the α‐transition associated to the SS of the TPU).…”

“…Over the last decades, the production of renewable materials as an alternative to petroleum‐based materials has attracted considerable attention from both academic and industrial groups. From these renewable materials, multiphase systems with advanced behaviors can be developed such as the biocomposites where both, matrices and fillers are bio‐based . Recent studies carried out by our group on thermoplastic polymers synthesized from dimers of fatty acid (DFA), such as polyurethane (TPU) and polyamide (DAPA), has shown the great advantage of TPU‐DAPA blending, since TPU and DAPA present two distinct behaviors.…”

Biocomposites based on chemically modified cellulose fibers with renewable fatty‐acid‐based thermoplastic systems: Effect of different fiber treatments

Advanced biocomposites, based on binary and ternary systems, were developed with thermoplastic matrices such as thermoplastic polyurethane (TPU) and polyamide (DAPA) obtained from dimers of fatty acids, and cellulose fibers (CF). The CF were modified to display high interfacial adhesion and compatibility with the rather hydrophobic matrices. Different routes were considered such as grafting onto with prepolymers, or grafting from with aromatic isocyanate or fatty acid. An original approach of this work is to consider CF as a polyol with an equivalent hydroxyl index obtained by titration. In order to understand better the effect of each phase, the resulting modified CF were tested with neat TPU and DAPA matrices. The most promising fibers treatments were then tested with 80/20 and 50/50 wt %/wt % TPU/DAPA blends. Properties at the molecular and macromolecular scale were investigated. Improvement of the interfacial adhesion between the fibers and the polymers were observed. From the different grafting approaches tested, the best performing were the isocyanate-terminated prepolymer and the silane-terminated prepolymer modifications. In comparison with neat CF, modification with isocyanate-terminated prepolymer improved threefold the storage and Young's modulus of TPU biocomposites.

This work aims to investigate the dynamic behavior of polypropylene organoclay nanocomposites. The nanocomposite was obtained b\ mixing the polvpropvlene matrix with a mastcrhatch of polypropylene modified anhydride mateic and niontmorillonite organoclay (pp-nanocor). The dynamic behavior was investigated by using split Hopkinson pressure bars, at different strain rates and different temperatures. The obtained nanocomposite exhibits a good dispersion and a partially exfoliated morphology. To study the effect of nanocomposite dispersion and morphology on the dynamic behavior, another nanocomposite was prepared by melt mixing of polypropylene and a modified montmorillonite (dellite) (PP dellite). The dynamic property results far PP-nanocor .ihow an increase of both Young's modulus and yield stress with the increasing organoclay concentration. However, PP-detlite nanocomposites present poor mechanical properties compared with those of PP-nanocor.
