Abstract:

This paper describes the method of preparing the cationic monomer with acrylamide，2-chlovoethanol and dimethylamine. The homepolymer of N，N-dimethyl ethylacrylamido ammonium chloride，and the copolymers 'of acrylamide with DEAAAC are synthesized with prepared positive nitrogen cationic monomers. Besides the polymerization conditions are determined and some structure parameters of polymers are measured. In this paper the relations are also analyzied between the properties of swelling—prevention of clay used for mud and the composition of the copolymers. The paper concludes that the cationic degree of polymers can be adjusted by polymerization conditions according to different clay swelling—preventing requirements.

Key words: Cation, Polymer, Acrylamide, Ammonium chloride, Clay stabilization
