| Abstract: | Epoxy prepolymers were prepared via esterification reaction between acrylic acid rosin and 1,4-butanediol diglycidylether/1,6-hexanediol diglycidylether. Polyamide hardeners were synthesized via amidation reaction between acrylic acid rosin and diethylenetriamine/tetraethylenepentamine. Then a new series of polymers were obtained through the reaction between prepolymers and polyamide hardeners stoichiometrically. The tests showed the new polymers had moderate degree of hardness; cross cut test, less than 3; T-Bend, 0; impact resistance, more than 60kg•cm; chemical resistance, passed; and aging under ultraviolet lights for 30d, intact. |
