Abstract

Alkyd resins were prepared into four different sets by varying the percentage concentration
of the glycerol content. Various properties such as the viscosity, Surface drying time, solubility
and color of the alkyd resins were evaluated for the various sets. The alkyd resin with the highest
glycerol content was the most viscous, brownish in color and having the highest molecular
weight this is due to the ratio 1:3 oil to glycerol content.
