Abstract：The wetting ability of the solution of water-soluble cationic polymer NCP and the solution of HPAM (partial hydrolytic polyacrylamide) on the surface of Ca-montmorillonite was determined by a JF99A contact angle calcimetre. The former has a smaller contact angle than the latter. The results of relative wetting angle show that NCP has better hygroscopicity. On the other hand, when montmorillonite was saturately adsorbed by NCP and HPAM solutions and was disposed by filtrating, washing, drying and sieving, the results of contact angle in water solution show that the NCP–MT has better hygroscopicity than HPAM–MT.
