Title
(EN) METHOD FOR MAKING POLYAMIDE
(FR) PROCEDE DE FABRICATION DE POLYAMIDES
Abstract
(EN)
The invention concerns a method for making polyamide using a catalyst in the form of solid titanium dioxide particles with diameter less than 100 mn and which remains efficient in the presence of matting agents such as microparticulate titanium dioxide.
(FR)
L'invention concerne un procédé de fabrication de polyamide. Le procédé met en oeuvre un catalyseur sous forme de particules solides de dioxyde de titane de diamètre inférieur à 100 nm et qui reste efficace en présence d'agents matifiants tels que le dioxyde de titane microparticulaire.
