Abstract
Aqueous emulsions used as binders in solvent-free paint formulations have to cope with the challenge to guarantee an excellent film formation and appearance as well as good properties. One strategy to fulfill these contradictory requirements is the employment of pure poly(acrylate) resins synthesized by emulsion polymerization. Kinetic studies involving free radical emulsion polymerization of methyl methacrylate (MMA)-co-n-butyl acrylate (BA) are carried out, so that the effect of BA on polymerization of MMA can be interpreted. In this study, the effect of emulsifier and initiator on the kinetics of polymerization was studied. The polymers were characterized using different analytical tools. The surface tension and contact angle of latexes were also measured by varying the concentration of monomer feed ratios. The results indicated that the incorporation of comonomer enhances the properties of coating formulation of polyacrylates.
