Synthesis of novel modified acrylamide copolymers for montmorillonite

In this paper, acrylamide copolymers were used as coagulant with cationic, anionic groups or both of them simultaneously. Consequently, in order to clarify the relationship between inhibitive properties, sedimentation volume measurement, SEM (scanning electron microscope), XRD (X-ray diffraction) and contact angle were adopted.

Recent advances of modified polyacrylamide in drilling technology

The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

Synthesis and properties of poly(acrylamide-co-N

A new anionic polymer poly (acrylamide-co-N-vinylpyrrolidone-co-sodium p-styrene sulfonate) (abbreviated as PANS) is synthesized by using acrylamide (AM), N-vinylpyrrolidone (NVP) and sodium p-styrene sulfonate (SSS) as monomers and used as filter loss agents.
