A new type of toughened epoxy polymer based on epoxy cresol novolac re
sin (ECN) and carboxy terminated polybutadiene (CTPB) liquid functiona
l rubber has been studied. ECN has been synthesized in the laboratory
and CTPB used was also of indigenised origin. Rubber modified epoxies
were characterized with the help of differential scanning calorimetry
(DC), dynamic mechanical analysis (DMA) and scanning electron microsco
py (SEM) techniques.
