The research progresses of cationic polymers containing dimethyldiallylammonium chloride(DMDAAC) as chain members were reviewed in this paper. With the double bonds which were able to participate in addition polymerization as the main line, the homo- and co-polymerizations of DMDAAC were summarized based on its molecular structure and physical chemical properties. The synthesis of DMDAAC-based polyacrylamide, copolymer with specific functional groups and modified natural products were discussed in detail. And the features of research work completed until now were also pointed out. Finally, it had been suggested that new polymers containing DMDAAC should be synthesized by molecular structure design and modification to meet the needs of their application indifferent fields. However, the further application researches of these polymers would be also important to promote the development of such polymers.
