Structural parameters characterizing the course of curing bisphenol A diglycidyl ether with hexamethylenediamine and 4,4′‐diaminodiphenylmethane in the pre‐ and postgelation stages were determined. Conversion at the gel point, concentration of the tertiary amino groups, and number average molecular weights agree fairly well over a broad range of the stoichiometric ratios of functionalities with the values calculated according to the procedure described in Part I (Dušek, llavský, and Luňák, J. Polym. Sci.: Symp. 53, 29 (1975). A satisfactory agreement was also obtained for lightly crosslinked gel prepared with an excess of the amino component. The optimum values for the reactivity (rate constants) ratio of hydrogen on the secondary and primary amino groups are 0.6–0.7 for hexamethylenediamine and 0.35–0.45 for 4,4′‐diaminodiphenylmethane. The agreement between the course of reaction and the assumed model indicates that not far from the gel point, and at a reaction temperature above the glass transition temperature, the diffusion control does not play any major role and a nonhomogeneous course of the curing reactions is not likely. The authors are indebted to M. Mach, and J. Klaban for the mechanical and spectroscopic measurements.
