New
epoxy resins were obtained from aniline/o-cresol/formaldehyde resins by
reaction with epichlorohydrin in large excess. The obtained resins were characterized
by elemental analysis, IR and 1H-NMR spectroscopy. Thermal stability
of aniline/o-cresol/formaldehyde resins and of the cured products made through
the curing reaction between epoxy resins and their
aniline/o-cresol/formaldehyde resins was also investigated by thermogravimetric
analysis (TG). Thermal studies showed the formaldehyde resins and cured
polymers have the same thermal behaviour.
Key Words:
multifunctional epoxy resins, crosslinking reaction, thermal properties
