Abstract

Nanoemulsion copolymers are stable liquid-in-liquid dispersions. Smaller particle sizes tend to valuable properties such as high surface area per unit volume, gloss, washablity, viscosity, and stability. So, new nano-styrene acrylate copolymers based on 2- Ethyl Hexyl Acrylate monomer by using Two different surfactants were prepared by emulsion polymerization, and formulated as a binder for water based paints to get useful properties. These nanoemulsion copolymers also confirmed by IR, GPC, DSC, TGA, TEM and zeta potential. The prepared nano copolymer showed enhancement in solid content, viscosity, and suitable glass transition temperature for coating formula. Finally, based on the results we compared between the prepared nano copolymers as a binder with the commercial styrene acrylate copolymer. The results obtained indicated that the prepared nanocopolymers can be used as a good binder for paints to improve all the film properties and mechanical properties of paints
