This monomer was subsequently employed in the synthesis of thermoplastic 1K (one component) acrylate polymers. These polymers are applicable in varnish and paint formulations, offering superior coating features, including increased gloss, enhanced adhesion, improved visual appeal, and robust impact resistance. The synthesized GRA served as a bio-based monomer in thermoplastic acrylate compositions at ratios of 2.5%, 5.0%, and 10.0%. The synthesized monomer and its resultant polymers were studied using gel permeation chromatography (GPC) and Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR). The thermal characteristics of the polymers were analyzed using a differential scanning calorimeter (DSC). The coating properties, including adhesion, gloss, hardness, drying times, and impact resistance, were evaluated and studied. The results indicate that increasing the quantity of gum rosin monomers in the polymers reduced the glass transition temperatures from 30.18 °C to 24.12 °C, which enhanced impact resistance and improved adhesion to metal surfaces. The adhesion is nearly doubled on metallic surfaces. Paints formulated with increased amounts of bio-based gum rosin exhibit exceptionally high gloss values, rapid drying times, and superior aesthetics compared to standard formulations. In comparison to the binders employed in currently available paints, the polymer containing gum rosin acrylate monomers can be utilized to manufacture paints and varnishes with enhanced coating capabilities. By the way, the paint formulations can be prepared without any addition of plasticizer.}, number={1}, publisher={Zonguldak Bülent Ecevit Üniversitesi}, organization={İZEL KİMYA}
