All reactions were carried out in aqueous media, except for the synthesis of polyacrylic acid, where the medium was n-butanol. Hydrogen peroxide, potassium persulfate, and benzoyl peroxide were used as initiators. The copolymers were purified by removing homopolymers. The homopolymers and copolymers...

In order to control the polymerization process, acrylic acid is usually mixed into an aqueous solution of less than 40%, and the polymerization temperature is usually controlled at 50~150 ℃ in the preparation of polyacrylic acid. The commonly used initiators are ammonium persulfate and sodium ...
About 25% of polyacrylic acid is used for detergents and dispersants. Polyacrylic acid is considered to be a first mucoadhesive polymer and the protonated form at an acidic pH is responsible for mucoadhesion. It is used as artificial tears to treat dry eye syndrome. Polyacrylic acid forms the ...
Polyelectrolyte complex based on chitosan and acrylic acid monomer by photoinitiated free-radical polymerization in the absence of crosslinker showed a large transition in swelling in response to changes in pH of surrounding medium. Their ability to swell arises from polyelectrolyte interactions and molecul...
