Influence of Tetrahydrofuran on Epoxy−Amine Polymerization

摘要: The objective of this work is to understand the influence solvent tetrahydrofuran (THF), a hydrogen bond acceptor, on epoxy−amine polymerization reactions. cure kinetics diglycidyl ether bisphenol A (DGEBA) and 4,4‘-methylenebiscyclohexanamine in presence THF as was monitored using Fourier transform infrared (FTIR) spectroscopy near-infrared (NIR) region. FTIR analysis showed that remained chemically inert during mechanistically based two-parameter catalytic model for intrinsic developed. This adequately described system absence THF. investigated by varying monomers weight ratio at 60, 50, 40 °C. Results given temperature kinetic rate constants decreased with increasing content up critical composition practically constant above com...
