Abstract

The invention relates to a method for the production of poly(meth) acrylate particles with a particle diameter of 1-15 .mu.m, where the monomers M are polymerized according to the method of batch polymerization, with 20-50 parts by weight of monomer M in a liquid medium LM, consisting of 55-100% by weight of mineral oil, and with the addition of 0.1 to 5 parts by weight of a polymer emulsifier E and 0.05-5 parts by weight of a radical initiator.
