Kinetic study by FTIR, TMA, and DSC of the curing of a mixture of DGEBA resin and γ‐butyrolactone catalyzed by ytterbium triflate

Abstract: A mixture of diglycidylether of bisphenol A (DGEBA) and ␥-butyrolactone (␥-BL) was cured in the presence of ytterbium triflate as a catalyst. The kinetics of the various elemental processes that occur in the curing process were studied by means of isothermal curing in the FTIR spectrometer. The kinetics of the contraction during the curing was also evaluated by TMA. In both cases, the kinetics was analyzed by means of isoconversional procedure and the kinetic model was determined with the so-called compensatio… Show more

“…The present work aims at studying in detail the kinetics of the copolymerization of a DGEBA epoxy resin with a spiranic bislactone, 1,6-dioxaspiro [4,4]nonan-2,7-dione (s(gBL)), and test the efficiency of several anionic initiators which are already used for the homopolymerization of DGEBA and other epoxy resins [15][16][17][18][19] and the copolymerization of epoxides with cyclic carbonates, [20][21][22] namely 1-methylimidazole (1MI), 4-(N,N-dimethyl)aminopyridine (DMAP) and 1,5-diazabicyclo[4.3.0]non-5-ene (DBN). Scheme 2 depicts the structures of these initiators.…”

“…The kinetic triplet (pre-exponential factor, activation energy, and the kinetic model) of the curing was determined using integral isoconversional nonisothermal kinetic analysis, Kissinger-AkahiraSunose equation, combined with the Coats-Redfern procedure. Details of the kinetic methodology are given in previous studies [21]. Microhardness was measured with a Wilson Wolpert (Micro-Knoop 401MAV) device (Massachusetts, USA) following the ASTM D1474-98 (2008) standard procedure.…”
