Abstract
Acetone-Formaldehyde (AF) resin having methylol groups (‒CH2OH) has been prepared and condensed with resorcinol (R) in the presence; of alcoholic alkali catalyst at varying ratios of AF:R; 1:1, 1:1.5 and 1:2. The resultant AF-R resins were characterized by elemental analysis, IR spectral studies, number average molecular weight (Mn) estimated by non-aqueous conductometric titration and thermogravimetry. The curing study of AF-R resins with Hexamethylenetetramine (HMTA) was monitored by Differential Scanning Calorimetry (DSC) and kinetic parameters were evaluated. The glass reinforced composites based on AF-R-HMTA system have also been prepared and characterized.
