Fully bio-based materials based on thermoplastic starch (TPS) were developed starting from corn starch plasticized with glycerol. The obtained TPS was further blended with five pine resin derivatives: gum rosin (GR), disproportionated gum rosin (dehydroabietic acid, RD), maleic anhydride modified gum rosin (CM), pentaerythritol ester of gum rosin (LF), and glycerol ester of gum rosin (UG). The TPS–resin blend formulations were processed by melt extrusion and further by injection moulding to simulate the industrial conditions. The obtained materials were characterized in terms of mechanical, thermal and structural properties. The results showed that all gum rosin-based additives were able to improve the thermal stability of TPS, increasing the degradation onset temperature. The carbonyl groups of gum rosin derivatives were able to interact with the hydroxyl groups of starch and glycerol by means of hydrogen bond interactions producing a significant increase of the glass transition temperature with a consequent stiffening effect, which in turn improve the overall mechanical performance of the TPS-resin injected moulded blends. The developed TPS–resin blends are of interest for rigid packaging applications.

“…In the 21st century, the crisis of petroleum resources has become one of the biggest problems and the development of polymers based on biomass materials is believed to be an effective way to deal with it . Biobased epoxy resins derived from various kinds of biomass materials have been reported, including aliphatic vegetable oil and isosorbide, aromatic cardanol, rosin, phloroglucinol, 2,5‐furandicarboxylic acid, eugenol, lignin and its derivatives . However, the integrated performances of most biobased epoxy resins are inferior to those of petroleum‐based diglycidyl ether of bisphenol A (DGEBA) resin; this greatly limits applications of biobased epoxy resins in cutting‐edge fields.…”

Developing biobased epoxy resin with high renewable carbon content and outstanding integrated performance is beneficial for both sustainable development and applications in cutting-edge fields. Herein, a biobased epoxy monomer (TEUP-EP) with high renewable carbon content (100%) was synthesized from renewable eugenol with a sustainable process; TEUP-EP was then blended with 4,4 ′ -diaminodiphenylmethane (DDM) to develop a new biobased epoxy resin (TEUP-EP/DDM). The integrated performance of TEUP-EP/DDM resin was studied and compared with that of petroleum-based diglycidyl ether of bisphenol A (DGEBA)/DDM resin. Compared with DGEBA/DDM resin, TEUP-EP/DDM resin has much better integrated performance and not only exhibits a glass transition temperature about 26 ∘ C higher and a 24.4% or 57% increased flexural strength or modulus, but also shows outstanding flame retardancy. Specifically, the limiting oxygen index increases from 26.5% to 31.4% and the UL-94 grade improves from no rating to the V-0 level; moreover, the peak heat release rate and total heat release decreased by 63.1% and 57.4%, respectively. All these results fully prove that TEUP-EP/DDM is a novel biobased high performance epoxy resin. The mechanism behind these attractive integrated performances is discussed intensively.

“…Rosin derivatives may serve as alternatives to petroleum‐based aromatic compounds or cycloaliphatic compounds that are generally used to modify polymers and improve their thermal and mechanical properties . The hydrogenated phenanthrene ring, as a characteristic functional group of rosin, significantly affects the hydrophobic and thermomechanical properties of polymers . Moreover, as the primary structural unit of target polymer, the huge hydrogenated phenanthrene ring structure can effectively block the winding of molecular segments, which increases the intermolecular spacing and free volume in polymer molecules .…”

A rosin‐based monomer with thermally crosslinkable benzocyclobutene groups was synthesized in this study. The structure of the monomer was examined using mass spectroscopy, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy. An amorphous crosslinked network with dielectric constant of 2.71 and dielectric loss of 0.0012 at 30 MHz was formed when the monomer was polymerized at high temperature (> 200 °C). The polymer film exhibits surface roughness (Ra) of 0.337 nm in a 5.0 × 5.0 μm2 area and the water contact angle of 110°. In addition, results from thermogravimetric analysis indicate that the polymer has T5% = 402 °C, and differential scanning calorimetry measurements show that the glass transition temperature is at least 350 °C. Results from nanoindentation tests show that the hardness and Young's modulus of the polymer are 0.418 and 4.728 GPa, respectively. These data suggest that this new polymer may have potential applications in electronics and microelectronics. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48831.
