The PCM cationic polymer clay stabilizer was synthesized by reaction of non-ionic monomer B and cationic monomer DAC.

In this paper, the quaternary ammonium type cationic polymers prepared by our lab was used as emulsifier to emulsify AKD wax, and also PAC was used to increase the charge of the emulsion.

A new determination for hydrolysis degree of partly hydrolysis polyacrylamide was introduced in this study,which is based on the interaction between anionic polymers and cationic polymers.

Recent progress in synthesis of cationic polymers is reviewed in this paper.

Effect of cationic polymers on performance of ink-jet memorial material;

Using cationic polymer for treating the produced water of oilfields;

The use of cationic polymer for plugging channellings and controling permeability of polymer-flooding reservoirs;

Synthesis and evaluation of the small cation polymer used in completion fluid;

The non-solid completion fluid is composed of the clay stabilizer with the high cation polymer PTA and low cation polymer,Na_2SO_3 as inhibitor whose mass ratio is 0.

The result shows that the jointed application of cation polymer with inorganic gel breaker can ensure that percolate possess good transparency, and can achieve good efficiency.
