Abstract
Cycloaromatic polyamines based on aniline, 4,4′-diaminodiphenylmethane and formaldehyde have been synthesized varying the molar ratio of aniline and formaldehyde keeping the amount of 4,4′-diaminodiphenylmethane constant via a single-step process, coded as PO1, PO2 and PO3. The resinous material of polyamines has been employed for curing studies of commercially available epoxy resinsw. The effect of time, temperature and the concentration of polyamines as curing agent have been studied. The epoxy specimens were further used for testing different dielectric properties such as resistivity, dielectric strength, dissipation factor and dielectric constant with an objective of their application as dielectric materials.
