In the present study we investigated the performance and selectivity of terephthalic acid (TA) as a trapping molecule for the laboratory quantification of photogenerated *OH in synthetic water (where the organic and inorganic concentration is perfectly controlled) adopted as a proxy of natural atmospheric water (i e cloud droplets) TA reacts with *OH to yield 2-hydroxyterephthalic acid (TAOH)

Properties of Alkyd Resins

However unsaturated acids such as Linolenic acid also increase the yellowing tendency of alkyds whereas alkyds made with nondrying oils (low degree of unsaturation) or their fatty acids have excellent color and gloss stability One of the important attributes of alkyd resins is their good compatibility with many other coating polymers For example vinyl resins i e copolymers of vinyl
