Synthesis of the Hydroxyl-Containing Poly(dimethyl siloxane) Modified Polyacrylate Core-Shell Latex and the Application as a Novel Binder for Pigment Printing of Fabric

A core-shell latex based on methyl methacrylate, n-butyl acrylate, and methacrylic acid was synthesized, and the core of which was modified by hydroxyl-containing poly(dimethyl siloxane). Glycidyl methacrylate was empolyed as one of monomers in the shell and served as a cross-linker when the core-shell latex was used as an binder of the pigment printing. The chemical structure of the copolymer was characterized by infrared spectrum. The stucture and the particle size of the core-shell particles were characterized by transmission electron microscopy, nanoscale granularity analysis, and differential scanning calorimetry. The latex was used as a binder in pigment printing of fabrics.
