Cation Pam ( Polyacrylamide ) Acrylic Acid Polymer Acrylic
Cation Pam ( Polyacrylamide ) Acrylic Acid Polymer
Cationic polyacrylamide is a white granule and it is a linear high molecular compound which is soluble in water. It is nontoxic, odorless and hygroscopic. Its outstanding feature is the high hydrophilicity which enables it dissolves in water at any ratio while insolubilizes in organic solvents like ethanol and acetone.
Polymer Properties Database
The hydrated PAM is a soft gel that is used in gel electrophoresis and as a super water-absorbing polymer (SAP's). Even though these polymers are called polyacrylamide, they are often copolymers of acrylamide and one or more other monomers. The most important co-monomer is acrylic acid or sodiumacrylate.

Synthesis and characterisation of a polyacrylamide
A polyacrylamide-polyacrylic acid copolymer hydrogel was prepared by the controlled hydrolysis of polyacrylamide in an alkaline solution of 10% sodium hydroxide. The structure and composition of the resulting copolymer hydrogel was approximately two acrylic acid units for every acrylamide unit.
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, typically using N,N '-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further.
PDF MSDS • Anionic Polyacrylamide • "Snow"
Anionic Polyacrylamide is a white, granular, odorless polymer that yields a gel-like material with the addition of water. It is insoluble in water and causes extremely slippery conditions when wet. Although not regulated as a hazardous material, the respirable dust is potential respiratory tract irritant.
What is Polyacrylamide|PAM FAQ
Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other chemical species, such as an acrylic acid or a salt thereof. The main consequence of this is to give the 'modified' polymer a particular ionic character.
Anionic Poly-Acrylamide (aPAM)
ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer retention aids typically have molecular masses in the range of 5 to 20 million grams per mole.
The Chemistry and Properties of Poly(Acrylamide-acrylic Acid
Poly(acrylic acid-acrylonitrile) resin p(AA-AN) was prepared by gamma-irradiation initiated copolymerization of acrylic acid (AA) with acry-lonitrile (AN) in aqueous solution according to Equation 5 .
Acrylate monomers, used to form acrylate polymers, are based on the structure of acrylic acid, which consists of a vinyl group and a carboxylic acid ester terminus or a nitrile. Other typical acrylate monomers are derivatives of acrylic acid, such as methyl methacrylate in which one vinyl hydrogen and the carboxylic acid hydrogen are both replaced by methyl groups, and acrylonitrile in which ...
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

Self-Healing Poly(acrylic acid) Hydrogels with Shape Memory
A promising strategy to design synthetic hydrogels with the ability to self-heal is to substitute the covalently cross-linked polymer chains by supramolecular ones. Although supramolecular hydrogels generally exhibit rapid self-healing without the need for any stimulus, they suffer from low mechanical strength which prevents them from any stress-bearing applications.
