High solids-content nanosize polymeric microlatexes made by microemulsion copolymerization at ambient temperature

Abstract

The microemulsion copolymerizations of acrylic acid (AA), acrylamide (AM), N-methylol acrylamide (NMA), methylmethacrylate (MMA), butyl acrylate (BA) and acrylonitrile (AN) initiated by the redox initiator ammonium persulfate (APS) and N, N, N′, N′-tetramethylethylenediamine (TMEDA) at ambient temperature were investigated. With this process high solids-content (44.0 wt%) and small (less than 50 nm) particle diameter copolymer latexes were attained. The effects of surfactants, the mechanical stabilities and application properties as an environmentally friendly self-crosslinking pigment printing binder with multifunctional groups were studied.
