摘要： The invention relates to a method for polymerising ethylenically unsaturated monomers by free-radical initiated emulsion polymerisation in an aqueous medium in a polymerisation reactor, wherein the inside walls and optionally also the fittings in the reactor are coated by applying a deposit-inhibiting product before the reactor is filled, characterised in that the surfaces that are to be coated with deposit-inhibiting product are treated with an acid solution.

摘要： The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.
