Mechanism of Alkali-thickening and Behaviour of Flow of opolymer Containing Acrylic Acid Emulsions

Abstract

Abstract: In this paper, a series of styrene, butyl acrylate and acrylic acid copolymer latexes were synthesized by semi-batch emulsion copolymerization.Aqueous ammonia titration curves and rheologicl properties of latexes were discussed.It was found that effect of aqueous ammonia on alkali-thickening of latexes containing carboxyl group increases with the increasing of contents of carboxyl group and of soft segmer in copolymer, and that with the increasing of amounts of aqueous ammonia, pHs and viscosity of latexes mostly have two sharp changes, and that latexes have various rheological properties because of different copolymer components and pHs.

Key words: Copolymer latex, Acrylic acid, Viscosity, Rheological property, Alkali-thickening
