Abstract

Special features of curing of epoxy resins derived from N,N-diglycidylamines and diffusion control of curing due to increase in Tg are discussed. The special features of amine curing of diglycidylamines include extensive formation of small rings and dependence of reactivities of epoxy groups. The relative intensity of etherification depends on curing temperature. Diffusion control of curing sets in when Tg approaches Tcure. The decrease of the rate constant is relatively steep. The decrease of segmental mobility and physical aging have been taken into account in the theoretical approach.
