摘要:
Polymerizable compositions containing titanium, manganese and/or zirconium salts of olefinically unsaturated, polymerizable carboxylic acids and other olefinically unsaturated comonomers and a radical polymerization initiator are suitable for the organic coil coating of metallic materials. These non-aqueous metal coatings are suitable for the chromium-free pretreatment of steel with excellent corrosion control.

摘要:
Described are water-in-oil emulsions containing an emulsion polymerizate which is soluble in or swells in water and an oil phase, consisting at least partly of monoether compounds, that is not miscible with water in all proportions. Also described are a method of preparing such emulsions and their use as agents for precipitation, sedimentation, and/or thickening.
