Synthesis and Dispersion Property of Poly(Butyl Acrylate-B-Acryl Amide) by Alkaline Reversed Atom Transfer Radical Polymerization in Emulsion: A Novel Amphiphilic Binder

Abstract

The hydrophilic property of acrylate copolymer is very important for the dispersion and adhesion ability in many fields such as pigment printing and dyeing of textiles. Poly(butyl acrylate-b-acryl amide) was synthesized by successive reversal atom transfer radical polymerization of butyl acrylate and acryl amide in emulsion. The structure of the copolymer was characterized by infrared spectrum and nuclear magnetic resonance. By adding alkaline salt, the molecular weight and its distribution of the block copolymer were controlled. The dispersion ability of acrylic copolymer was improved by acryl amide segment; thus, preparation of a novel amphiphilic binder is expected to be helpful to solve the problems of the current binders.
