Polyacrylic acid - Wikipedia

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 .

Do poly(acrylic acid)/poly(acrylamide) microgels show smart behavior?

Author to whom correspondence should be addressed. Poly (acrylic acid)/poly (acrylamide) microgels with an IPN structure demonstrate smart behavior with dual pH and temperature responsiveness. Both factors are determinative for human physiology.

Can atomistic model predict glass transition temperature and mechanical properties of polyacrylamide/polyacrylic acid?

Volume 3, article number 8, (2021) A new comprehensive simulation model at atomistic level is proposed to investigate the miscibility and predict the glass transition temperature (Tg) and mechanical properties of polyacrylamide/polyacrylic acid (PAAm/PAA) weakly interpenetrating polymer networks (IPN).

Is acrylamide interpenetrating a weakly cross-linked network based on acrylic acid?

We propose a theoretical model based on the molecular modelling theory for the purpose of expecting physical behavior of a system consisting of interpenetrating a weakly cross-linked network based on acrylamide with an another weakly cross-linked network based on acrylic acid.

Where was polyacrylamide (PAAM) purchased?

Polyacrylamide (PAAM) (Mw > 5,000,000) was purchased from BDH Laboratory reagents, Poole, England. All reagents were used as received. 4.2. Methods 4.2.1. Synthesis of P (AA-co-AAM)/PAAM pIPNs P (AA-co-AAM)/PAAM pIPNs were synthesized by free radical polymerization.

Can acrylamide be grafted onto starch molecular structures through free radical polymerization?

The study details the grafting of acrylic acid and acrylamide onto starch molecular structures through free radical polymerization. This graft copolymerization enhances water absorption capacity and alters physical, morphological, and mechanical characteristics, making it a novel avenue for the chemical modification of carbohydrate polymers.
