“…[ 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. In some very inspiring recent research, the L-lysine based ethyl ester l -lysine diisocyanate was compared to petrol-based hexamethylene diisocyanate, and isophorone diisocyanate in terms of reactivity and final properties of the PU [ 37 , 38 , 39 , 40 , 41 ] and even fully renewable thermoplastic poly(ester urethane urea)s were produced [ 42 ]. More studies on enzymatic breakdown/biodegradability of (biobased) PUs are conducted in recent years proving the importance of environmentally friendly PU applications [ 9 , 43 , 44 , 45 , 46 , 47 ].…”

Polyurethanes (PUs) are an important class of polymers due to their low density and thermal conductivity combined with their interesting mechanical properties—they are extensively used as thermal and sound insulators, as well as structural and comfort materials. Despite the broad range of applications, the production of PUs is still highly petroleum-dependent. The use of carbohydrates in PU synthesis has not yet been studied extensively, even though, as multihydroxyl compounds, they can easily serve as crosslinkers in PU synthesis. Partially or potentially biobased di-, tri- or poly-isocyanates can further be used to increase the renewable content of PUs. In our research, PU films could be easily produced using two bio-based isocyanates—ethyl ester L-lysine diisocyanate (LLDI] and ethyl ester l-lysine triisocyanate (LLTI)—, one commercial isocyanate—isophorone diisocyanate (IPDI), and a bio-based white dextrin (AVEDEX W80) as a crosslinker. The thermal and mechanical properties are evaluated and compared as well as the stability against solvents.

“…Alternatively, polyester-based TPEs have gained increasing attention due to their biocompatibility and biodegradability [4,5]. α,ω-Hydroxyl terminated telechelic polyesters (e.g., poly(ε-caprolactone) (PCL), poly(lactide-co-glycolide)) with a moderate MW (3000-6000 g mol −1 ) are effective precursors for the synthesis of hydrolytically degradable TPU elastomers [6][7][8]. On the other hand, polyesters with a narrow polydispersity would be useful for biomedical and pharmaceutical applications, e.g., as biodegradable implant materials and drug delivery systems [9,10].…”

Heterogeneous Double Metal Cyanide Catalyzed Synthesis of Poly(ε-caprolactone) Polyols for the Preparation of Thermoplastic Elastomers

et al. 2021

A series of polycaprolactones (PCLs) with molecular weights of 950–10,100 g mol−1 and Ð of 1.10–1.87 have been synthesized via one-pot, solvent-free ring-opening polymerization (ROP) of ε-caprolactone (CL) using a heterogeneous double metal cyanide (DMC) catalyst. Various initiators, such as polypropylene glycol, ethylene glycol, propylene glycol, glycerol, and sorbitol, are employed to tune the number of hydroxyl end groups and properties of the resultant PCLs. Kinetic studies indicate that the DMC-catalyzed ROP of CL proceeds via a similar mechanism with the coordination polymerization. Branched PCLs copolymers are also synthesized via the DMC-catalyzed copolymerization of CL with glycidol. The α,ω-hydroxyl functionalized PCLs were successfully used as telechelic polymers to produce thermoplastic poly(ester-ester) and poly(ester-urethane) elastomers with well-balanced stress and strain properties.

“…12 A high degree of selectivity towards the synthesis of linear polyol-polyesters has also been reported by exploiting Novozym 435 (immobilised Candida antarctica Lipase B). 1,4,18 Selective derivatisation of the primary hydroxyl groups has been identified when employing compounds like D-sorbitol [23][24][25][26] a feature which could prove very valuable in the design of renewable hydrophiles. Nonetheless, high costs associated with enzymes hinder their widespread industrial use, and this is an important factor to consider when synthesising surfactants for commercial applications.…”
