Abstract :
In the present work, to study the effects of side group on water absorption, a series of novolac epoxy resins was cured with esterified a phenol novolac resin and phenol novolac resins separately. Thus, the hydroxyl group of phenol novolac resin was replaced by CH/sub 3/COO- group, C/sub 3/H/sub 7/COO/spl rho/oup and C/sub 6/H/sub 5/CH/sub 2/COO- group, and the cured resins were named as EP, EPA, EPB and EPP, respectively. FTIR showed that there were no hydroxyl groups but ester functional groups in the cured resins cured. with the esterified phenol novolac resins. The influence of the side groups on the water absorption behavior of the cured epoxy resins was investigated using gravimetric method, DSC, and corrosion test.
