“…In the meantime, the PBS crosslinking reaction's enthalpy values (Δ H ) also increased with DCP content increasing. When DCP content was 4 wt%, the enthalpy value was 35.11 J/g; when DCP content increased to 8 wt%, the corresponding enthalpy value was increased to 69.64 J/g, higher enthalpy value indicated the higher crosslinking degree of PBS 33 …”

“…When DCP content was 4 wt%, the enthalpy value was 35.11 J/g; when DCP content increased to 8 wt%, the corresponding enthalpy value was increased to 69.64 J/g, higher enthalpy value indicated the higher crosslinking degree of PBS. 33 Figure 2B showed the TGA curves of PBS and crosslinked PBS, from which we can find the crosslinked PBS exhibit excellent thermal resistance to oxidative stability and high char yields. The temperature corresponding to 5% weight loss (Td 5 ) under nitrogen was 610.8 C, and no apparent weight losses were observed below 550 C. Then the weight loss process was prolonged, with resulting char yields of 85.6%.…”

This paper fabricated the cross‐linking poly(butylene succinate) foaming materials with high expansion ratio, high mechanical strength, and high degradation rate though cross‐linking and molding compression methods. With dicumyl peroxide content increasing, complex viscosity, and storage modulus appear to increase tendency. The properties of cell size, distribution, mechanical properties, and thermal conductivity all appear the first increasing and then decreasing trend with dicumyl peroxide content increasing. When dicumyl peroxide concentration is 6 wt% and azodicarbonamide concentration is 1 wt%, pure cross‐linking poly(butylene succinate) foaming material's expansion ratio and compression strength could reach 7.03 and 5.61 MPa, respectively. In addition, this pure cross‐linking poly(butylene succinate) foaming material has high degradability, and the degradation ratio could get 80% in alkaline aqueous solution.

“…The -CRC-groups in the monomers and polymer chains usually undergo complex reactions, including cyclotrimerization, Diels-Alder reaction, and a few addition reactions to convert to phenyl rings, aromatic fused rings, and polyene structures at a high temperature. 16,21,34 In our case, the thermal curing reactions of the three aromatic diynes and resins were monitored by differential scanning calorimetry (DSC), and the results are depicted in Fig. 3.…”

A novel linear silicon‐containing hybrid polymer with C  C and SiH linkages, diphenyl‐dihydroethynyl‐silane (DPHES), had been conveniently synthesized and well characterized. The thermal curing, crosslinked structure and pyrolysis behavior were studied by DSC, Fourier transform infrared (FTIR), and Pyrolysis‐gas chromatography/mass spectrometry (Py‐GC/MS). The results suggest the crosslinked structures consist mainly of phenyl and aromatic fused rings, which are formed through cyclotrimerization, addition reaction, and hydrosilylation reaction. The thermal properties indicate that the crosslinked DPHES exhibits excellent thermal stability with the temperature at 5% weight loss are higher than 572 and 509 °C under nitrogen and air atmosphere, respectively. The fluorescence emission spectra show DPHES and its crosslinked product also have moderate fluorescence properties, emitting purple light, and visible blue light, respectively, which further verified the structure of DPHES. These results suggest that DPHES has the potential to be used as light‐emitting materials with excellent thermal properties. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47403.
