    Polyacrylamide - Wikipedia

    Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. 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.

    Hydrolysis of polyacrylamide and acrylic acid-acrylamide

    The hydrolysis of acrylamide-acrylic acid copolymers has been studied as a function of pH and of the initial composition of the samples. Our experimental results confirm the intramolecular catalysis by neighbouring undissociated carboxylate groups for 3 < pH < 5, as already demonstrated by Smets et al., and the catalysis of OH − ions with autoretarded kinetics for pH > 11.

    Polyacrylamide/acrylate Polymer - online catalog source

    General Description : A copolymer of acrylamide and acrylic acid (normally supplied as the sodium salt) that is cross-linked sufficiently to render it insoluble in water but which retains its hydrophilic nature. It therefore can absorb a very large amount of water, swelling proportionately as it does so.

    The FTIR spectra confirm the formation of copolymer of acrylamide and acrylic acid as is evident from bands that appeared in the range of 3100–3500 cm −1 (O–H and N–H stretching) 34. The absorption located in the regions 3350-3330 cm -1 and 3200-3185 cm -1 corresponds to the asymmetric and symmetric NH 2 stretching vibrations from

    Acrylamide and Cancer Risk - National Cancer Institute

    Acrylamide is a chemical used primarily to make substances called polyacrylamide and acrylamide copolymers. Polyacrylamide and acrylamide copolymers are used in many industrial processes, such as the production of paper, dyes, and plastics, and in the treatment of drinking water and wastewater, including sewage.

    Ecotoxicological effects of polyacrylate, acrylic acid, polyacrylamide and acrylamide iii Summary Some fertilizers can contain polymers composed of acrylamide (AMD) or acrylic acid (AA). Cross-linked polyacrylamides (PAM) and polyacrylates (PAA) can absorb huge amounts of water, thus belonging to the class of Superabsorbent Polymers (SAP).
