摘要：
Producing spherical polymers having a weight-averaged average particle diameter of 1 to 50 &mgr;m using a seed/feed process comprising the following steps: a) suspension of a monodisperse spherical seed in an aqueous phase, b) addition of at least one monomer and an initiator, c) polymerization of the monomer, of which there is at least one, wherein the seed consists of a polymer having a comb structure, gives rise to products having a particularly narrow grain size distribution.
