    Abstract: Zpusob výroby polyamidu spocívá v tom, ze se polymerizace výchozích monomeru nebo výchozích oligomeru provádí za prítomnosti alespon jedné slouceninyvzorce (I), ve kterém znací R funkcní skupinu R.sup.8.n., která nese 1 az 4 stejné nebo rozdílné amidotvorné skupiny R.sup.7.n.; R.sup.1.n. je H, C.sub.1.n. az C.sub.20.n.-alkyl, cykloalkyl, benzyl, OR.sup.6.n., kde znací R.sup.6.n. H, C.sub.1.n. azC.sub.20.n.-alkyl, cykloalkyl, benzyl; R.sup.2.n., R.sup.3.n., R.sup.4.n., R.sup.5.n. jsou nezávisle na sobe C.sub.1.n. az C.sub.20.n.-alkyl; n je prirozené císlo vetsí nez 1, pricemz piperidinové deriváty vázané na R jsou se zretelem na substituenty, to znamená R.sup.1.n., R.sup.2.n., R.sup.3.n., R.sup.4.n. a R.sup.5.n., rozdílné nebo stejné. Takto vyrobené polyamidy se pouzívají k výrobe nití, vláken, fólií, plosných útvaru a tvarových teles.

    Abstract: Disclosed is a method for producing a polyamide containing titanium dioxide pigments. Said method is characterized by the fact that titanium dioxide pigments are dispersed in an initial mixture containing water and caprolactam by means of a device comprising a dispersion chamber, a disk-shaped rotor that is disposed inside said dispersion chamber, a stator that is provided with radial openings, is arranged within the dispersion zone of the dispersion chamber, and is connected to the rotor, a substance inlet located on each side of the rotor, preferably with a respective axial duct section such that the two flows of substance are combined in the peripheral edge area of the rotor disk, and a product outlet which is placed on the outer edge of the dispersion zone of the dispersion chamber, by feeding the titanium dioxide pigments to the dispersion chamber through one of said substance inlets while feeding the initial mixture containing water and caprolactam to the dispersion chamber through the other of said substance inlets, whereby a product mixture containing water, caprolactam, and the used titanium dioxide pigment is obtained via the product outlet, and the product mixture is polymerized so as to obtain a polyamide containing titanium dioxide pigments. Also disclosed are polyamides obtained according to the inventive method and the use of such polyamides as a masterbatch.
