Stability of kaolin dispersion in the presence of lignin-acrylamide polymer - ScienceDirect
In one study, the hydrodynamic diameter of anionic polyacrylamide in alumina dispersion reported to be increased from 19.5 to 25.1 nm with the pH increase from 3 to 9 (Wisniewska et al., 2015a). Hence, the smaller size of KAM at pH 4 ( Table 4 )
Polyacrylamide Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked,
An enhanced immobilization of BSA biomolecule on anionic hydrogels: swelling and adsorption modeling
In this work, we focus on how the anionic co-monomer acidity affects the sensitive protein adsorption, their uptake and the swelling behavior in BSA solution of the acrylamide-based hydrogels. For this, copolymers based on acrylamide (AAm) and

- What is partially hydrolyzed polyacrylamide?
- Partially Hydrolyzed Polyacrylamide (Liquid) is a liquid emulsion of acrylic co-polymers designed to improve performance of all types water based mud systems (WBM), which imparts shale and bore-hole stability, viscosity modification, lubricity, selective flocculation and assists with fluid loss control.
- Which polymers are used in oil fields?
- Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.
- How does PHPA mud control shale?
- For shale-control, PHPA can supposedly seal microfractures, coat shale surfaces with a film that retards dispersion and disintegration. The viscosifying effect of the dissolved high molecular weight polyacrylamide polymer controls the rheological behavior of the PHPA mud.
- What is a PHPA mud system?
- The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. PHPA can be used in mud systems varying from low solids to weighted muds systems utilizing fresh or saltwater. PHPA is a white granular powder, anionic in nature having a specific gravity of 1.25 to 1.40 and a bulk density of 40 to 46 lb/ft 3.
