| Abstract: | Abstract: Different waterborne hyperbranched acrylated-maleinized alkyd resins (HBRAAM) were synthesized by modifying a hyperbranched alkyd resin (HBRA) with three different butylmethacrylate–maleic anhydride copolymers (BMA–MA) in the presence of p-toluenesulfonic acid (PTSA). The HBRAAM resins were characterized by using infrared analysis, iodine value, hydroxyl value, vapor pressure osmometry (VPO), dynamic light scattering (DLS), acid value, rheological analysis, differential scanning calorimetry, adhesion, flexibility, drying time, gloss, hardness and chemical resistance to solvents. The iodine value and hydroxyl value decreased with the amount of BMA–MA copolymer employed in the synthesis. Infrared analysis, VPO, and hydroxyl values allowed us to conclude that the reaction between HBRA resins and BMA–MA copolymers occurred. The viscosity of the HBRAAM resins was between 50.5 and 468Pas. All HBRAAM resins presented good properties of adhesion, flexibility, drying time, gloss, hardness and chemical resistance.
