Assignee:

BAKER HUGHES INCORPORATED - Houston TX

International Classification:

C08G 73/06
C08J 3/12

Abstract:

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.
