A method of manufacturing a hemiaminal dynamic covalent network (HDCN) comprises reacting a diamine and formaldehyde in the presence of a reaction medium comprising a polar solvent and a nonpolar solvent at a temperature of about 15° C. to about 100° C. to form the HDCN. A composition comprising the produced HDCN can be molded to form various articles comprising poly(hexahydrotriazine)s.
