摘要：
Water-soluble hydroxyl functionalized hyperbranched polyester (WH-HP) resin was synthesized using pentaerythritol, pyromellitic dianhydride, phthalic anhydride, and 1,1,1-tris(hydroxymethyl) propane. The synthesized WH-HP was characterized by spectroscopic (FTIR and NMR) as well as thermal (TGA and DSC) analysis. WH-HP and hexa methoxy methyl melamine (HMMM) resins were mixed in different mole ratios (1: 2.5, 1: 5, 1: 7.5, and 1: 10), coated on mild steel panel, and cured by baking at 110 degrees C for 1 h. These coating compositions were evaluated for their mechanical and anticorrosive properties. It was observed that coating composition having 1: 5 mol ratio (WH-HP: HMMM) has shown very good mechanical and anticorrosive properties compared to the rest.
