Abstract

In this study, a modified method for preparing low viscosity alkyd resin was suggested. For this purpose the preparation of sunflower oil-based alkyd resins were achieved into two steps. First sunflower oil and glycerol were reacted to form partial glycerides, and then, after removing free glycerol, esterification reaction was achieved between partial glycerides and anhydride. Glutaric, maleic, phthalic and succinic anhydride were used. Sunflower oil alkyd resins were also prepared by classical method. The results obtained were compared with each other. By the modified method low viscosity and good film properties resins could be prepared. (C) 2004 Elsevier B.V. All rights reserved.
