Synthesis and Characterization of Polyurethane Coatings derived from Polyols Synthesized with Glycerol, Phthalic Anhydride and Oleic Acid

Polyester polyols, with various oleic acid contents were used in the preparation of polyurethane (PUR) coatings. The polyols were designated as Alk28, Alk40 and Alk65, in which 28,40 and 65 represents the percentages of oleic acid in the respective formulations. The physical properties of the polyol...
