Effect of Thermoplastic Polyurethane on Morphology and Properties of Materials Based on Epoxidian Resin and Triethylenetetramine
Year: 2024
Type: article
Abstract: It has been found that curing of ED-20 epoxy resin with triethylenetetramine modified with T-ECOPUR thermoplastic polyurethane allows to obtain materials with water absorption not higher than 1 % wt. and the value of marginal wetting angle up to 113 deg. This is probably due to the presence of microheterogeneities formed by polyurethane chemically bonded with polymer matrix due to the interaction of hydrogen atom at nitrogen of urethane group and oxygen of oxirane cycle.
