Beschreibung
Zusammenfassung:	The present invention relates to a polymodal polymer composition having homogeneous as well as heterogeneous particles formed by radical emulsion polymerization of monomers from category A which forms homopolymers with Tg above 15 °C and monomers from category B which forms homopolymers with Tg below -15 °C. The polymer composition is composed of at least two different populations of particles, differing in mean particle size value by at least a factor of 2. Thus, the two different populations of polymer particles in the polymer composition differ with respect to size and monomer composition of the particles.
