“…As expected, the increase of oil content leads to poor tensile strength and Young's modulus due to the increasing free volume from the triglyceride chains. The dimensions of the Young's modulus and tensile strength and the tendency to increased values with shorter aliphatic chain or more rigid structures, are in agreement with published plant oil‐based epoxy thermosetting networks . No tendency is observed for the elongation at break.…”

[44][45][46] No tendency is observed for the elongation at break. Its variation of <8% is within the error of the measurement due to the low thickness of the films (0.13-0.20 mm).…”

Lignin and plant oils—two highly available renewable feedstocks—are cured via olefin metathesis to produce thermosetting polymer films with tunable mechanical properties. Therefore, an organosolv lignin, allylated in a recently described sustainable approach, is used. For the first time, unmodified plant oils are reacted with a lignin derivative. An increasing lignin content as well as an increasing amount of polyunsaturated fatty acids in the plant oil structure lead to higher Young's moduli and higher cross‐linking density. Stress–strain measurements reveal ductile behavior of the prepared films. Only a lignin content over 70% leads to brittle materials. To improve the overall sustainability of this approach, dimethyl carbonate is investigated as sustainable solvent for film formation, leading to materials with similar Young's moduli and tensile strength, but lower degree of cross‐linking if compared to the more volatile solvent dichloromethane.

Poly(l‐lactic acid) (PLLA) was blended with a series of four‐armed poly(ϵ‐caprolactone)‐block‐poly(d‐lactic acid) (4a‐PCL‐b‐PDLA) copolymers in order to improve its crystallization rate and mechanical properties. It is found that a higher content of 4a‐PCL‐b‐PDLA copolymer or longer PDLA block in the copolymer lead to faster crystallization of the blend, which is attributed to the formation of stereocomplex crystallites between PLLA matrix and PDLA blocks of the 4a‐PCL‐b‐PDLA copolymers. Meanwhile, the PDLA block can improve the miscibility between flexible PCL phase and PLLA phase, which is beneficial for improving mechanical properties. The tensile results indicate that the 10% 4a‐PCL5k‐b‐PDLA5k/PLLA blend has the largest elongation at break of about 72% because of the synergistic effects of stereocomplexation between enantiomeric PLAs, multi‐arm structure and plasticization of PCL blocks. It is concluded that well‐controlled composition and content of 4a‐PCL‐b‐PDLA copolymer in PLLA blends can significantly improve the crystallization rate and mechanical properties of the PLLA matrix. © 2017 Society of Chemical Industry

“…A bio-based polymeric material from ESO and poly(L-lactic acid) (PLLA) has also been reported to show shape memory behavior. 46 PolyESO/PLLAs were synthesized by acid-catalyzed curing of ESO in the presence of PLLA. PLLA was scarcely reacted with ESO during the reaction and was dispersed in the ESO based polymer network.…”

The increasing interest of academic and industrial sectors in the use of bio‐based materials mirrors the overwhelming need for replacing, as much as possible, petroleum derived chemicals, reducing the negative environmental impact derived from their usage. Vegetable oils fulfill this goal extremely well, because of their worldwide availability, large volume production at comparatively low prices and versatility of the modifications and reactions in which they can participate to produce a large variety of different monomers and polymer precursors. Further reactions of these chemicals can lead to very different types of final materials with varied applications. It is because of this remarkable versatility that many review articles have appeared during the last few years; many of them have dealt with the various routes for vegetable oil modification and options for polymer synthesis, whilst others were dedicated to the analysis of the properties of the derived materials, generally focusing on structural properties. In this review, we focus on the capabilities of vegetable oils to be modified and/or reacted to obtain materials with functional properties suitable for use in coatings, conductive or insulating materials, biomedical, shape memory, self‐healing and thermoreversible materials as well as other special functional applications. © 2015 Society of Chemical Industry
