Synthesis of oligotetramethylene oxide diamines containing cycloaliphatic moieties as the hardeners for compounds with terminal epoxy groups
摘要
New oligoether diamines were synthesized via the step of obtaining oligoether diacrylates, followed by their subsequent reaction with 3-aminomethyl-3,5,5-trimethylcyclohexylamine. A series of urethane-containing elastomers based on them was obtained. The polymers were evaluated by differential scanning calorimetry, and their deformation and strength characteristics were also estimated. It was demonstrated that a low glass transition temperature is characteristic of all the polymers.
