  • Nanometric TiO2-catalyzed production of polyamides
    Patent number: 6593448
    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 TiO2), the catalyst therefor comprising solid nanometric TiO2 particulates having diameters of less than 100 nm.
