Claims (7)

1. Способ экстракции полиамидных частиц или полимерных частиц, содержащих полиамиды, водными экстрагирующими средствами, отличающийся тем, что в качестве водного экстрагирующего средства используют водные растворы аминонитрилов.1. The method of extraction of polyamide particles or polymer particles containing polyamides, aqueous extracting means, characterized in that as the aqueous extracting agent using aqueous solutions of aminonitriles. 2. Способ получения экстрагированных полиамидных частиц или полимерных частиц, содержащих полиамиды, полимеризацией аминонитрилов и экстракцией полученных таким образом полиамидных частиц или полимерных частиц, содержащих полиамиды, водными растворами аминонитрилов. 2. A method for producing extracted polyamide particles or polymer particles containing polyamides by polymerizing aminonitriles and extracting the thus obtained polyamide particles or polymer particles containing polyamides with aqueous solutions of aminonitriles. 3. Способ по п. 1 или 2, отличающийся тем, что в качестве аминонитрилов используют ω-аминонитрилы. 3. The method according to p. 1 or 2, characterized in that as the aminonitriles use ω-aminonitriles. 4. Способ по одному из п. 4, отличающийся тем, что в качестве ω-аминонитрилов используют ω-аминоалкилнитрилы. 4. The method according to one of p. 4, characterized in that as the ω-aminonitriles use ω-aminoalkylnitriles. 5. Способ по одному из пп. 1-4, отличающийся тем, что экстракцию проводят непрерывно и полиамидные частицы или полимерные частицы, содержащие полиамиды, и водное экстрагирующее средство проходят в противотоке. 5. The method according to one of paragraphs. 1-4, characterized in that the extraction is carried out continuously and the polyamide particles or polymer particles containing polyamides, and the aqueous extractant passes in countercurrent. 6. Способ по п. 5, отличающийся тем, что экстракцию проводят в экстракционной колонне, разделенной на две зоны, при этом в первой зоне экстракция проводится водным экстрагирующим средством при циркуляции, и затем во второй зоне экстракция проводится водой в противотоке. 6. The method according to p. 5, characterized in that the extraction is carried out in an extraction column, divided into two zones, while in the first zone, the extraction is carried out by an aqueous extracting means during circulation, and then in the second zone, the extraction is carried out in countercurrent water. 7. Способ по п. 1, отличающийся тем, что в случае полиамида речь идет о Полиамиде-6. 7. The method according to p. 1, characterized in that in the case of polyamide we are talking about Polyamide-6.
