Abstract
The invention relates to a non-aqueous dispersion of organic polymer particles in a reactive diluent. Said non-aqueous dispersion can be obtained in that at least one monomer is polymerized in the reactive diluent, forming the organic polymer particles, wherein the reactive diluent does not participate in said polymerization due to the orthogonal reactivity thereof relative to the monomers, but comprises a functionality allowing later targeted polymerization. Depending on the organic polymer particles or reactive diluents used, the non-aqueous dispersion can be used in multifaceted applications having a wide range of application profiles. In order to produce said non-aqueous dispersion, polymerization of at least one monomer in a stirred tank reactor in the presence of a reactive diluent is particularly suitable, wherein the conversion is performed at a stirring speed of at least 2 m/s, wherein the ratio of the stirrer diameter to the vessel diameter is set to 0.3-0.80 and the distance from the stirrer to the vessel floor is set to 0.25 to 0.5 times the stirrer diameter. The invention provides multifaceted advantageous applications, particularly as an impact strength modifier, particularly in films, and as an adhesive, as casting resin, or as paint. A particularly advantageous application is producing a molded part or a semi-finished polymer product.
