Hydroxylated Sunflower seed oil was synthesized and copolymerized by blending with commercial polyvinyl acetate. The determined physical properties of the copolymer composite (ie SSO/PVA) compared to the pure PVA revealed improvements in its physical properties such as poor gloss, low water resistance and flexibility. Comparison of these results with the literature values shows that physico-chemical properties of the SSO/PVA copolymer binder were in conformity. The SSO/PVA was then used as a binder in the production of emulsion paint. The results of the physicochemical analysis of the emulsion paint showed that the pH, the Viscosity, Flexibility, Adhesion, Opacity, Hardness test, Tackiness, Resistance to blistering, and the drying time were also within range of the standard. It showed good resistance to acidic, alkaline and salt medium compared to the pure PVA paint. This study may therefore, introduce a novel binder to the coating industry.
