Enthused by the ever growing demand for sustainable and green based materials in responding to applications based on macromolecules, an attempt was made in seeking a bio‐resin (Terpene). Herein, we report the functionalization of bio‐resin with natural rubber (NR) to produce new sustainable and greener functional polymer. Bio‐resin functionalized NR was prepared by melt mixing using di(2‐tert butyl peroxy isopropyl) benzene initiator. Structure elucidation of the bio‐resin functionalized NR was established by proton nuclear magnetic resonance and Fourier transform infrared spectroscopy, respectively. Bio‐resin functionalized NR facilitates the augmented interaction with highly dispersible silica. Amended state of highly dispersible silica dispersion has been achieved in the absence of toxic process oil, expensive silane coupling agent and conventionally used zinc oxide. Remarkable improvement in overall properties corroborated with various meticulous characterization including nanoindentation, rheological, physico‐mechanical and small angle X‐ray scattering using Becauge model, etc. The dynamic mechanical properties of the greener polymer demonstrated low rolling resistance coupled with high traction. More decisively, the macromolecule system toned up sparingly in the presence of the bio‐resin. Our contribution facilitates a novel avenue to develop sustainable high‐performance elastomeric macromolecule. Copyright © 2017 John Wiley & Sons, Ltd.

“…For all of these results, we realized the reason of these phenomena and interaction between reactant and solvent depicted in Figure . According to the nucleophilic addition mechanism, the increased polarizability of the epoxy ring of ECl would make the attack of the amino group of DA‐DHPZ on the epoxy ring more easily …”

“…In Figure A, the exothermic peak temperature of TGDDM/30 phr TEPZ/40 phr DDS was higher than the one of others. This result indicated that more reactions would occur at higher temperature, and the thermal stability of the resultant may be improved . As shown in Figure B, the sample with lower DDS content had higher exothermic peak temperature than the others.…”

A novel tetrafunctional epoxy (TEPZ) was synthesized by “one spot two steps” method, and the effects of solvents, reaction temperature, and mole ratios of reactants on the reaction conversion were systematically investigated. The results demonstrated that the solvents participating in the reaction were the most crucial factor for high conversions. After curing, TEPZ/4,4′‐diaminodiphenyl sulfone (DDS) system exhibited better thermal stability compared with famous N,N,N′,N′‐tetraglycidyl‐4,4′‐diaminodiphenyl methane (TGDDM)/DDS analog. When TEPZ is blended with TGDDM/DDS, the initial decomposition temperature of TGDDM/TEPZ/DDS hybrid elevated from 348°C to 362°C. The storage modulus and the glass transition temperature were sensitive to curing procedure and concentration of DDS. While the system consisted of 100 phr TGDDM, 30 phr TEPZ, and 40 phr DDS, the storage modulus and glass transition temperature increased significantly compared with those of TGDDM/DDS, and the impact strength increased by 31.6% simultaneously. Such enhancement could be ascribed to the structural feature of phthalazinone in TEPZ, which formed stable interpenetrating networks during thermal cure procedure.

“…The same group also developed a sustainable route to prepare eugenol-based difunctional epoxy resin with a fully aromatic ester backbone, higher reaction activation energy, slower curing rate, a high T g , unusual intrinsic flame retardancy, low smoke production, and significantly improved mechanical properties. 26 The study on renewable eugenol-based epoxy resin has a great significance and initiates a new avenue to explore sustainable high-performance thermosets. Apart from the applications mentioned above, Derek L. Patton reported eugenol-derived catechol-functionalized thiolene polymer networks as photocurable adhesives.…”
