It enables the determination of the amount of free and available hydroxyl functionality in the alkyd resin. This parameter will influence the following properties of the resin: Polarity of the resin. Water resistance - a high OH view.

5、(PDF) Current State of Alkyd Resin Synthesis and Characterization

Alkyd resins are made by reacting polyols (like glycerol or pentaerythritol) with dicarboxylic acids (like phthalic anhydride), then modifying the mixture with fatty acids or drying oils.

Preparation and evaluation of high

By partially substituting 1,3,5-tris- (2-hydroxyethyl) cyanuric acid for glycerol as the polyol, new modified alkyd resins having a wide range of oil length and hydroxyl content were produced.

Preparation of excellent

Water-borne alkyd/acrylic hybrid resins with varied maleic anhydride (MA) content were synthesized from the reaction between alkyd intermediate (AK) and maleic anhydride modified acrylic prepolymer (AC) followed by neutralization of carboxyl groups with triethylamine.
