Abstract
(Co)polyamides, for example the polyamides 6 and 66, are prepared via the improvedly catalyzed polycondensation of (co)polyamide-forming (co)monomers, even in the presence of normally catalyst-inhibiting matting agents (e.g., microparticulate TiO ), the catalyst therefor comprising solid nanometric TiO particulates having diameters of less than 100 nm.
