    摘要： The present invention relates to a method to prepare a polymer dispersion using an aqueous substantially surfactant-free emulsion polymerization process comprising a seed and a feed stage, in which seed stage at least one ethylenically unsaturated monomer, having a water-solubility of at least 0.3 g/l at polymerization conditions, is polymerized in the presence of an addition fragmentation chain transfer agent and a hydrophilic free radical initiator to form a seed polymer that is substantially insoluble in water and in which feed stage at least one ethylenically unsaturated feed monomer is added to the seed polymer to form polymer particles. With this method a polymer dispersion can be obtained having at least 25 wt. % solid contents in combination with an average polymer particle size smaller than or equal to 300 nm. The invention further relates to a polymer dispersion obtainable by a surfactant-free emulsion polymerization process, a film-forming composition, preferably a coating composition, comprising such a polymer dispersion and coated articles coated with the coating composition. Further, the invention relates to a polymer particle powder obtained from the polymer dispersion and powder coating compositions.

    摘要： The present invention relates to a crosslinkable composition comprising at least one crosslinkable component and a latent base crosslinking catalyst, which crosslinkable composition has a solids content of typically at least 55 wt (dry weight after crosslinking relative to the total weight of the crosslinking composition) wherein the latent base catalyst is a substituted carbonate salt according to formula (I) wherein X+ represents a non acidic cation, preferably a quaternary ammonium or phosphonium, and wherein R is hydrogen, alkyl, aryl or aralkyl group. The invention relates in particular to a composition crosslinkable by Real Michael Addition (RMA) reaction wherein a component with at least 2 activated unsaturated groups and a component with at least 2 acidic protons C—H in activated methylene or methine groups, preferably malonate react and crosslink to each other in the presence of the base catalyst. The invention further relates to a coating composition comprising the crosslinkable composition according to the invention, a novel catalyst composition and to the use of said catalyst composition according to the invention as a latent base crosslinking catalyst in coating compositions, preferably in RMA crosslinkable compositions.
