摘要：

Chlorinated alkyds were synthesized by the direct chlorination of Albizia benth oil alkyd of 50% oil length. It was confirmed from IR spectroscopy that chlorine enters only into the aliphatic portion of the alkyd chain by addition and substitution reactions. The mechanical and chemical film properties of the unchlorinated and chlorinated A. benth oil alkyd were determined. The results revealed that the chlorinated resins possessed superior drying properties, scratch hardness, and water, acid and alkali resistances than the unchlorinated alkyds. While the impact resistance of the A. benth oil alkyd remained satisfactory, the flexibility and adhesion decreased on chlorination. (C) 2004 Published by Elsevier B.V.
