Abstract
Abstract of the Disclosure: Polymers of olefinically unsaturated monomers and solutions of these polymers are obtainable by a process in which the olefinically unsaturated monomers are polymerized in the presence of a free radical initiator in solution under polymerization conditions which are otherwise predetermined, in such a way that the solvent and/or a liquid part of one or more reactants of the polymerization batch are initially taken and heated to the polymerization temperature, and some or the total amount of the monomers to be polymerized is fed continuously to the agitated initially taken part of the polymerization batch via one or more feeds, with maintenance or initiation of the polymerization, in such a way that the outlet orifice of the one or more feeds is located below the surface of the initially taken liquid part of the polymerization batch.
