“…Limonene contains unsaturated endocyclic and exocyclic double bonds. Since endocyclic in double bonds in the limonene ring is more reactive and stable than exocyclic, endo peaks were observed in lower area in NMR results (Brum et al, 2013;Ren et al, 2015;Çankaya et al, 2019;. The data obtained from the 1 H-NMR spectrum were found to be in agreement with the polymers synthesized with limonene in the literature (Sharma & Srivastava, 2003;2004;2006;Singh & Kamal, 2012;Ren et al, 2015;Zhang & Dubé 2015;Çankaya et al, 2019;.…”

“…The system was kept in inert gas at 65°C for 24 h. The synthesized polymer was crystallized several times in ethyl alcohol (Figure 2). (Çankaya & Temüz, 2012;Çankaya et al, 2019; and the copolymer was characterized by spectroscopic methods FT-IR and 1 H-NMR (Figure 3 and Figure 4).…”

“…The FT-IR spectrum of the copolymer LIM-co-NPA is indicated in Figure 3. FT-IR (cm -1 , the most characteristic bands): 1673 (C=O amide stretch), 3311 stretch and 1595 bending vibration (N-H), 2980 and 2950 (C-Ar-H), 1504 asymmetric and 1330 symmetric stretch (NO2) (Sharma & Srivastava, 2003;2004;2006;Çankaya & Temüz, 2012;Singh & Kamal, 2012;Brum et al, 2013;Ren et al, 2015;Zhang & Dubé, 2015;Çankaya et al, 2019;Tanış et al, 2019;Zhang & Dubé, 2014). The clear observability of characteristic bands in the amide monomer and the absence of alkene bands in the monomers show that our newly synthesized polymer has formed and the literature also support this allegation (Coşkun et al, 2002;Kurt et al, 2019a).…”

D-limonene Sustainable Polymer Copolymer Synthesis and Characterization Thermal StabilityCopolymerization is a very important method in the synthesis of products having the physical and chemical properties sought in industrial sense. In this paper, the copolymerization of N-(4-nitrophenyl) acrylamide monomer with D-limonene was carried out and LIM-co-NPA copolymer was synthesized by free radical chain polymerization reaction. The structure of sustainable copolymer of limonene was chemically characterized by FT-IR, 1 H-NMR spectroscopic techniques. In addition, thermal stability of copolymer investigated by TGA/DTG/DTA simultaneous thermal analysis methods. The spectroscopic results are compatible with the amide or limonene polymers synthesized in the literature. From the important thermal results of the sustainable copolymer, it has been found that the initial decomposition temperature is 226°C, and the maximum decomposition temperatures is 329°C, glass transition temperature at 261°C and crystallization temperature at 340°C. It can be said that this promising sustainable copolymer is suitable for other mechanical, physical and biological study and research fields.

Bismaleimide and Biobased Limonene Copolymer Microspheres as Reactive Fillers to Fabricate Low-k, High-Toughness Cyanate Ester Resin Composites

Bismaleimide and biobased copolymer microspheres (BMPL) of bis[4-(4-maleimidoyloxy)phenyl]propane (BMIP) and limonene (LIM) with different compositions are synthesized via self-stabilizing precipitation copolymerization and applied as reactive modifiers of 2,2-bis(4-cyanatophenyl) propane (BADCy) resin. Due to the different reactivities of exo- and endocyclic vinyl groups in the LIM monomer, the content of the vinyl groups in the BMPL can be simply tuned by copolymerization temperature. There are some endocyclic double bonds of LIM in BMPL prepared at 75 °C but no observable endocyclic double bonds in BMPL prepared at 130 °C. The presence of LIM endocyclic double bonds in BMPL microspheres can effectively reduce the curing temperature of BADCy resin via the formation of chemical bonds between the BADCy matrix and BMPL microspheres but without expensing the heat resistance of the composites. The dielectric constant (ε) and dielectric loss (tan δ) of the BMPL/BADCy composite with the addition of 10 wt % of BMPL are 2.67 and 0.0034, respectively, at 106 Hz, which was much lower than those of pure BADCy (2.87, 0.0054). In addition, the maximum impact strength of the BMPL/BADCy composite at 10 wt % BMPL loading is 18.21 kJ/m2, which is 88.3% higher than that of pure BADCy. The BMPL/BADCy composite demonstrates low-k dielectric properties, high toughness, and thermal stability and has potential in the fields of electronic communication, aerospace, and aviation.
