Abstract
PURPOSE: To improve corrosion resistance and hardness by incorporating a resin into an aqueous coating compsn., said resin being obtd. by reacting a specified liquid polybutadiene with mercaptan cpd. to form suflide linkage, esterifying the product with aminoalcohol and treating the ester with an acid and an epoxy cpd.
CONSTITUTION: A liquid polybutadiene (a) having number-average molecular weight of from 500W5,000, pref. 700W4,000 and contg. 1,4-linkage of at least 40% is reacted with mercaptan cpd. (b) contg. carboxyl gp. such as thioglycol, thiopropionic acid to form sulfide linkage. The product is esterified at a temperature of from about 50W250°C with aminoalcohol such as monoethanolamine, butanol- amine. The ester is treated with an acid such as acetic acid, HCl and an epoxy cpd. The sulfur atom in the form of sulfide linkage is converted to sulfonium ion, thereby the product becomes water soluble or water dispersable. The product can be used as main component of desired aqueous coating composition.
