Abstract
A poly(meth) acrylic acid dispersion with an organic solvent as outer phase, the dispersed phase particles having a low polydispersity is obtained by the free radical polymerization of (meth) acrylic acid and optionally co-monomers, which bring about a cross-linking of the poly(meth) acrylic acid, in a nonpolar, organic solvent in the presence of stabilizers, costabilizers, and initiators. The stabilizer is a block copolymer.
