ABSTRACT:
A process for the continuous and discontinuous production of polycaprolactam is disclosed which includes the step of polymerizing, by anionic polymerization, .epsilon.-caprolactam to which suitable initiators and activators are added. The process may optionally include the addition of comonomers, pigments, electroconductive fillers, modifying polymers, inorganic fillers, reinforcing fibers, inorganic fillers and/or other additives to a dispersing media in which the polymerization takes place with polycaprolctam, copolymers or composites thereof being obtained in the form of particles. The foregoing additives may, for example, be added to the dispersing media dropwise with mechanical or convective stirring under controlled temperature conditions. The granulometric or morphological characteristics of the particles obtained are influenced by the nature, viscosity, temperature and the rate of stirring of the dispersing medium, as well as by the rate of feed of the caprolactam and the polymerization ingredients to the dispersing media and by the geometry of the polymerization reactor.
