Gelation kinetics of N,N＇ diallyl malonamide / acrylamide system is investigated by dilatometric technique. The effect of N,N＇diallyl malonamide concentration on the gelation reaction at 60 degrees C and at constant initiator concentration and the effect of temperature on the gelation reaction at constant crosslinker and initiator concentrations are investigated. Critical gelation times are determined in each case.
