20.500.12556/RUL-116744 The joint effect of amine and maleimide functional group in aminomaleimide on the curing kinetics and mechanical properties of epoxy resins A new epoxy curing system, combining amine and maleimide functionality into a single molecule, was introduced to broaden current state of the art as regards epoxy, amine and maleimide systems. Curing agent aminomaleimide was tested in the curing process of several aromatic and aliphatic epoxies. Prepared mixtures in different weight (molar) ratios were investigated by nonisothermal differential scanning calorimetry to study and compare curing kinetics of different epoxies. The apparent activation energy was determined by Kissinger method, while Friedman method accompanied by Malék statistical approach was used in confirming the autocatalytic nature of epoxy curing and additional maleimide polymerization at the excess amount of aminomaleimide. Thermo-mechanical properties were determined by dynamic mechanical analysis and the effect of aminomaleimide curing agent compared to curing agent containing only amino functional groups was evaluated. Aminomaleimide showed improvement in the glass transition temperatures and higher char yields due to the involvement of maleimide moiety in the curing process. In overall, aminomaleimide showed the positive one-molecule joint effect of the amino group, behaving as an accelerator, and maleimide group, a mechanical properties enhancer. epoxy amine maleimide curing kinetics thermal properties epoksi amini maleimid kinetika zamreževanja termične lastnosti true true true Angleški jezik Slovenski jezik Članek v reviji 2020-06-08 08:13:05 2020-06-08 08:18:50 2022-08-29 03:38:53 0000-00-00 00:00:00 2020 0 0 Str. 1-10 art. 178668 Vol. 690 2020 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2022-06-01 678.686 0040-6031 10.1016/j.tca.2020.178668 17850883 832516 RAZ_Rucigaj_Ales_2020.pdf RAZ_Rucigaj_Ales_2020.pdf 1 8397F08E3EF46743AA999BFD341A7C5F c952d423242612f89e90610ece2bb070b538bcc7586696b1f86862d455b1eeeb 004d90c8-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130416 https://www.sciencedirect.com/science/article/abs/pii/S0040603120303026 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130415 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
