Abstract

Clear, permanently refusible zinc and zinc-calcium resinates are made by (1) fusing a rosin containing at least about 7.5 per cent polymer with at least 5 per cent zinc oxide (or equivalent hydroxide or carbonate) in presence of a carboxylic acid or a salt thereof capable of reacting with abietic acid to liberate the acid, followed by further fusing with lime if a zinc calcium resinate is desired, or (2) fusing a polymer-containing rosin with lime, and further fusing with at least 5 per cent zinc oxide (or equivalent hydroxide or carbonate) in presence of a carboxylic acid or salt as above. The temperature of fusion may be 200-300 DEG C. Rosins specified are heat-treated gum or wood rosin or pine oleoresin (e.g. prepared according to Specification 351,583) or polymerised rosins prepared by use of zinc chloride, boron trifluoride, or sulphuric acid, or according to Specification 536,218. Catalysts specified are acetic, formic, lactic, tartaric, and citric acids or their metal or ammonium salts. In examples: (1) heat-treated rosin is fused with hydrated lime and then with zinc oxide in presence of acetic acid; (2) a zinc chloride polymerised rosin is fused with zinc oxide in presence of acetic acid.
