Abstract
The interaction of glycidyl esters of phosphorus acids (GEF) with aromatic amine hardeners has been studied. A comparative analysis of the reactivity of different GEF (triglycidyl phosphate (TGFT), diglycidyl methyl phosphate (DGMFT), diglycidyl methyl phosphonate (DGMFN)) has been carried out. The activity of amine hardeners in interaction with GEF has been also compared. Kinetic parameters for the curing reaction have been calculated using Thermokinetics software, and the mode of the interaction of phosphorus-containing epoxy oligomers with aromatic amines has been assessed. Complex structures have been optimized using DFT computations at the CAM-B3LYP/TZVPP level with accounting for solvent effects using the C-PCM model. Thermophysical and flame-retardant characteristics of cured phosphorus-containing epoxy polymers have been investigated. It has been shown that epoxy polymers based on GEF and amine aromatic hardeners have high values glass transition temperature. The resulting binder is self-extinguishing and displays promise for use in the RTM process.
