Title
(CS) Zpracování polyamidu kyselinou, anhydridem nebo aminem v plynné fázi
(EN) Treatment process of polyamide with acid, anhydride, or amine in gaseous phase
Abstract
(CS) Řešení se týká způsobu snižování obsahu koncových skupin polyamidu v pevném stavu zpracováním polyamidu kyselinou, anhydridem nebo aminem v plynné fázi. Řešení se dále týká dosažení odolnosti polyamidových vláken proti skvrnám snížením počtu aminových koncových skupin polyamidu a snížením počtu karboxylových koncových skupin, které snižuje objem regenerace výchozích monomerů během vytlačování.
