Abstract: A process for producing polymers by the ionogenic polymerization of lactams is disclosed, wherein the lactam monomer, in the liquid state, mixed with a catalyst and promoter is introduced into a heated mold, which rapidly rotates about an axis outside the mold, via a conduit disposed co-axially with respect to the axis and via a feed channel which extends from the conduit at an angle to the axis and the polymerized, molded object is automatically removed from the mold in a radial direction due to centrifugal force.

Abstract: An apparatus is disclosed for the preparation of high-molecularweight polymerization products by ionogenic catalytic polymerization of lactams, in which one portion of the monomer is mixed with a catalyst and another portion with a promoter for accelerating the polymerization, after which these two components are mixed in the liquid state at the upper end of a down pipe and introduced into a heated mould in which the polymerization takes place. When charging of the mold is stopped, the down pipe runs empty of the mixture to prevent hardening of the polymer where the mixing takes place.
