Abstract: 

Acetone-formaldehyde (AF) resin having dihydroxy functionality (-CH 2 OH) has been prepared and polycondensed with m-cresol (me) at equimolar ratio of AF:mC to produce acetone-formaldehyde-m-cresol (AF-mC) resin. The three component IPNs have been prepared from this acetone-formaldehydem-cresol (AF-mC) resin, diglyddyl ether of bisphenol-A (a commercial epoxy resin) and methyl methacrylate using simultaneous mode of IPN synthesis. The curing catalyst, hexamethylenetetramine, for AF-mC, radical initiators such as 2,2'-azobisisobutyronitrile for methyl methacrylate and curing catalyst, 4,4'-diamino diphenyl methane, for the epoxy resin were employed. The various proportions of three components were employed. All the IPNs were characterized in terms of their thermal stabilities with DSC, TGA. The glass fibre reinforced composites of produced IPN syrups have been fabricated and their chemical resistivity and mechani cal properties were evaluated.
