Abstract
Det blir fremskaffet en fremgangsmåte for fremstilling av en akrylkopolymerlatcks med forbedrede mekanisk- og skjærstabilitet, omfattende emulsjonspolymerisering av minst en etylenisk umettet monomer med opptil 23 kaiboner i nærvær av, basert på vekten av det totale monomerinnholdet, a) fra omlcring 0,05% til omkring 5,0% av et beskyttende kolloid med en molekylvekt på mindre enn 75.000 og b) fra omkring 0,01% til omkring 1,5% av minst en vaimoppløselig friradikal-polymerisasjonsinitiator. Denne lateksen gir beleggprodusenter fleksibilitet til enten å eliminere overflateaktive midler totalt fra belegget, eller å benytte små mengder derav.A process for preparing an acrylic copolymer lacquer having improved mechanical and shear stability is provided, comprising emulsion polymerization of at least one ethylenically unsaturated monomer with up to 23 kaibons in the presence of, based on the weight of the total monomer content, a) from about 0.05% to about about 5.0% of a protective colloid having a molecular weight of less than 75,000 and b) from about 0.01% to about 1.5% of at least one water-soluble free radical polymerization initiator. This latex gives coating manufacturers the flexibility to either completely eliminate surfactants from the coating, or to use small amounts thereof.
