The influence of ionic liquids on curing rheokinetics and properties of strengthening composition based on polyesterurethane rubber with epoxyurethane groups

A study of the influence of ionic liquids on the curing and properties of a strengthening composition based on polyesterurethane rubber with epoxyurethane end groups has been carried out. The catalytic activity of ionic liquids has been found to be dependent on the anion chemical structure and to increase as the anion size decreases. It has been shown that introduction of methylbenzylamine and ionic liquid (1-ethyl-3-methyl-imidazolyl dicyanamide) results in strengthening compositions with close mechanical properties, lifetime, swelling in transformer oil, and glass transition temperature.
