Polyacrylamide (PAM), High Molecular Weight (5,000,000–6,000,000 g/mol)
Polyacrylamide (PAM) is a high molecular weight, water-soluble polymer commonly used in aqueous systems for
viscosity modification, flocculation research, and gel-forming applications. This grade contains long polymer chains
that readily entangle in solution, contributing to high viscosity at relatively low concentrations.
High molecular weight polyacrylamide is frequently selected for laboratory research, formulation development, and
process studies where polymer chain length influences rheology and polymer–particle interactions.

Applications
Water Treatment and Flocculation Research
High molecular weight polyacrylamide is commonly evaluated as a flocculant polymer in research settings, where long
chains promote particle aggregation through bridging mechanisms.
Enhanced Oil Recovery (EOR) and Flow Studies
Polyacrylamide is used in polymer flooding and flow experiments to increase aqueous phase viscosity and study
mobility control in porous media models.
Gel Electrophoresis and Laboratory Hydrogels
Polyacrylamide is a standard material for gel electrophoresis and can form reproducible hydrogels used in analytical
separations. (Note: electrophoresis gels are formed from acrylamide monomer systems.)
Formulation, Rheology, and Materials Research
In formulation research, high molecular weight PAM is evaluated for its ability to modify viscosity, influence
texture, and enhance stability in aqueous systems.
FAQs
Common questions about Polyacrylamide (PAM), MW 5,000,000–6,000,000.
-
What is polyacrylamide (PAM) used for?
Polyacrylamide is a water-soluble polymer commonly used in aqueous systems for viscosity modification,
flocculation research, and hydrogel formation in laboratory applications.
-
How does high molecular weight affect polyacrylamide behavior?
Higher molecular weight polyacrylamide typically has longer chains, which increases chain entanglement and
can raise solution viscosity at comparable concentrations.
-
Is polyacrylamide the same as acrylamide?
No. Polyacrylamide is the polymer, while acrylamide is the monomer used to form certain gels.
-
Is this grade ionic or non-ionic?
This product is described as non-ionic polyacrylamide. Ionic grades are produced by incorporating charged
comonomers.
-
Does polyacrylamide dissolve directly in water?
Polyacrylamide is generally water soluble, but high molecular weight grades may hydrate slowly. Gradual
addition with adequate mixing is commonly used to reduce clumping.
