Macroreticular bead PAN/PVC IPN resins with cyano and chloro groups were synthesized by interpenetrating polymerization of acrylonitrile, or acrylonitrile and divinylbenzene into a macroporous polyvinyl chloride bead. The composition and structure of the bead IPN resins have been investigated by means of FT-IR, NMR, SEM, mercury porosimetry and elemental analysis. During the process of interpenetrating polymerization, the chain propagation obeys Bernoullian statistical law, and no grafting polymerization has been observed.The content of cyano group in the resulting IPN resins can be adjusted by the amount of acrylonitrile added.The morphology of the IPN resins basically resembles that of the polyvinyl chioride bead,whereas the pore structures vary to a certain degree.
