Acrylic Acid → Zinc acrylate

Participants

Reaction Conditions

Reaction Steps

A zinc acrylate polymer was prepared by the reaction of zinc oxide and naphthenic acid (acid value 200 mgKOH/g) with a carboxylic acid functional acrylic copolymer based on the monomers; Acrylic acid (25.0 mol %), Ethyl acrylate (62.9 mol %), Cyclohexyl methacrylate (9.6 mol %) and methoxy polyethyleneglycol methacrylate (MPEG350) (2.5 mol %). These components were mixed at a 1:1:1 molar ratio (zinc oxide:naphthenic acid:polymer carboxylic acid groups) in xylene/n-butanol (4:1 weight ratio) and heated and stirred at 95° C. until a clear solution was obtained resulting in a solution of zinc acrylate polymer of 45 wt % in xylene/n-butanol/water (41.7:12.3:1.0 wt %).
