THERMOGRAVIMETRY OF PHENOL-FORMALDEHYDE POLYCONDENSATES.

Abstract

For constant heating rate thermogravimetry of phenol-formaldehyde polycondensates, it proved necessary to first reduce procedural bias of kinetics. The ensuing method, limited largely by instrument accuracy and practical sample form, gave empirical kinetic parameters via two complimentary curve-fitting techniques. Close correlation with past results gave confidence to the validity of the rate parameters. Several invalid cases, such as for air pyrolysis, improper geometry or inadequate cure, were also briefly probed. (Author)
