    Abstract: Molded articles of polymerized lactams are prepared by pumping of a catalyst containing partial lactam melt at a temperature of .+-.1.degree. C. of a temperature in the range of 160.degree. C. to 170.degree. C. and a lower temperature activator containing partial lactam melt at a temperature of .+-.1.degree. C. of a temperature in the range of 160.degree. C. to 170.degree. C. to which activator addition is delayed relative to catalyst addition, with separate gear pumps to a mixing zone maintained between 170.degree. and 175.degree. C., the pumps connected to the mixing zone by straight feed tubes positioned at an angle of inclination to the horizontal of a maximum of 10.degree., each feed tube having a volume of at least one-third greater than the pump to which it is connected and form the mixing zone into a mold. At least part of the gases released are returned to the mixing zone by the tube systems and gear pumps. The products formed crumble on being heated to a temperature of approximately 220.degree. C. to 280.degree. C. and are free of bubble formations and shrink holes. Apparatus to carry out the method is also provided.
