Process for preparing bead polymers with particle size of 1 to 40 mym and molding materials containing this bead polymers, molded materials and PAMA-plastisols

摘要

the present invention relates to processes for the manufacture of perlpolymerisaten with a mean particle size in the range of 1 to 40 microns, wherein a polymerisierbare composition, at least 50 wt.% (meth) acrylate in aqueous phase is dispersed and polymerized.with a compound containing aluminium as well as stabilized dispersion in a schergeschwindigkeit 103 s 1 produced.;after the erfindungsgemu00e4u00dfen procedure produced perlpolymerisate own, in particular, for the production of formku00f6rper with matte finish. also, the perlpolymerisate beneficial in pama - plastisols, dentalmassen and manufacture of kunststofformen, in particular for the ceramic industry, are used.
