The neoprene and polyacrylamide system was studied at various blend ratios. Infra-red studies indicate the reactive nature of neoprene, polyacrylamide and their blends. Inter-crosslinking between neoprene and polyacrylamide segments occurs by chemical reaction through the imide groups formed from polyacrylamide and the halogen atoms of neoprene. Studies with a differential scanning calorimeter and a dynamic mechanical analyser clearly indicate the apparent incompatible nature of the blend and show it to be a three-phase system. The third phase is a compatibilized interfacial zone of inter-crosslinked material. Preferential etching of the phases with solvents is possible. A scanning electron microscopy study also confirmed the multiple-phase structure of the cured blends
