In addition, before polymerization (sometimes and during polymerization), only 3080% of the whole mixture used, used as a sulfonic acid emulsifier, is added. Under certain conditions, the total amount of the suspension stabilizer and the remaining 70-20% of the total sulfonic acid used as an emulsifier are used. The suspension stabilizer may be applied to the polymer formed after separation. A polymer is also suitable, in the preparation of which less than 20% of the total amount of sulfonic acid used is added before polymerization (sometimes during polymerization), and the remaining amount of sulfonic acid (80% and above) is applied to the polymer obtained after separation. The suspension polyvinyl chloride thus obtained with the following characteristics: 60-70 Value K Bulk density, g / l 350-500 Plasticizer absorption capacity, weight,% Average grain size, IUM Grain dispersion distribution, wt%;
    fractions 4 33JUM 60-98 fractions 33-63 m 2-35 fractions 63-125 jUM 0.45 fractions 0.05 determine the content of free sulfonic acid, for example, by acidimetric titration (see below) and add 10-70 vaf, % of the amount of at least one sulfonic acid salt described above for the complete proton transfer from the free acid.
    At. the determination of the added amount is based on the fact that the hydrogen ion (proton) of the free sulfonic acid splits off exclusively from the nitrogen atom in the molecule of the added compound (compounds and that for each nitrogen atom there is one hydrogen ion (proton). The amount of added given below in va.%, based on free sulfonic acid. When adding less than 10 vaK.% of the compound defined by formula (I), positive effects are practically not observed. If more than 70 vat is added,%, there is a deterioration in the mechanism properties of sintered finished articles from the molding material. Such deterioration of mechanical properties is also observed when compounds of formula (1) with less than six carbon atoms are added. Compounds of formula (I) having more than 60 carbon atoms can be used in principle, but their need to be applied in a fairly large amount, so that their use for reasons of economy is not advisable. Nitrogen-containing compounds are added after the termination of polymerization either to the aqueous suspension of the polymer or to the water-containing y, or dry polymer. The amount of acid in the mixture is determined immediately before the nitrogen-containing compound is added to the polymer at the appropriate processing stage. For better distribution, nitrogen-containing compounds can be used in the form of solutions, suspensions or dispersions in liquids, such as water, or aliphatic alcohols with 1-4 carbon atoms.
    It is advisable to set the polymerizate into motion during the addition, for example, by stirring, shoveling, agitating, centrifuging, spraying and grinding. Since the polymer is a solid or (due to some moisture content) semi-solid substance, it is recommended that the nitrogen compound be added to the polymer by spraying or blowing as a fine powder .- As the polymer is finely mixed with
    Nitrogen-containing compound (s) can, if necessary, separate water by conventional methods, for example, by suction, centrifugation and / or drying, for example, in a drying cabinet, in a fluidized bed or in a continuous polymer dryer to obtain a dry polymer and continue to recycle. The dry product is used without any additional additives at all.
