Title
(EN) TREATMENT OF POLYAMIDE WITH GAS PHASE OR ACID, ANHYDRIDE OR AMINE
(KO) 기체 상태의 산, 무수물 또는 아민을 이용한 폴리아미드의처리
Abstract
(EN)

The end group content of polyamide in the solid state may be reduced b treating the polyamide with gas-phase acid, anhydride, or amine. Stain- or dye-resistant polyamide fibers can be made by reducing the number of amino end groups. Reduction in the number of carboxylic end groups reduces the rate of regeneration of starting monomers during extrusion.

(KO) 고체 상태의 폴리아미드의 말단기 함량은 폴리아미드를 기체 상태의 산, 무수물 또는 아민으로 처리하여 감소시킬 수 있다. 내오염성 또는 내염색성 폴리아미드 섬유는 아미노 말단기의 수를 감소시켜 제조할 수 있다. 카르복실 말단기의 수의 감소는 압출 동안 출발 단량체의 재생율을 감소시킨다.
