DOI: 10.1002/app.44223
Abstract: During free radical photopolymerization, with an increasing degree of conversion, the viscosity increased and vitrification occurred. The unreacted double bonds had difficulty diffusing to the reactive site in the vitrifying polymer. However, the free radicals… read more here.

DOI: 10.1021/acsomega.1c02338
Abstract: Radical photopolymerization has attracted significant attention for manufacturing products with complicated structures. Herein, the synthesized 1,4-bis(4-bromophenyl)-2,5-bis(4-nitrophenyl)-1,4-dihydropyrrole[3,2-b]pyrrole (PyBN) is found to show varying photoactivity upon irradiation at different wavelengths. PyBN affords two main absorption bands, and… read more here.

DOI: 10.1039/c8py00166a
Abstract: Curcumin is attractive in photopolymerization especially in cationic photopolymerization, because of its broad absorption and nontoxic properties. Curcuminoid (CMD) is a linear diarylheptanoid and can be considered as a derivative of curcumin. Based on the… read more here.

DOI: 10.3390/polym13111801
Abstract: Three novel visible-light absorbing benzophenone-based hydrogen acceptors (BPD-D, BPDM-D and BPDP-D) were designed on the basis of a donor–benzophenone–donor structural backbone. Mono or diketone units and double diphenylamine electron-donating groups in para-or meta-positions were introduced… read more here.
