Abstract
Acetone-Formaldehyde (AF) resin having methylol group (—CH2OH) has been prepared and condensed with m-cresol (MC) in the presence of alcoholic alkali catalyst at varying ratios of AF:MC; 1:1, 1:1.5 and 1:2. The resultant AF-MC 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-MC resins with Hexamethylenetetramine (HMTA) was monitored by Differential Scanning Calorimetry (DSC) and kinetic parameters were evaluated. The glass reinforced composites based on AF-MC-HMTA system have also been prepared and characterized.
