Abstract

본 발명은 내열성이 우수한 폴리아미드의 제조방법으로서 폴리아미드에 망간염을 첨가시킬 때 할로겐화 나프탈린 유도체를 병용사용함으로써 망간염 첨가로 인한 섬유의 열화를 방지하도록 하는 방법이다.The present invention is a method for producing a polyamide having excellent heat resistance, which is used to prevent deterioration of fibers due to the addition of manganese salt when a manganese salt is added to the polyamide in combination.

카프로락탐에 망간염을 첨가하여 폴리아미드를 제조함에 있어서 하기식으로 표현되는 할로겐화 나프탈린 유도체를 함께 첨가하는 내열성 폴리아미드의 제조방법.A method for producing a heat-resistant polyamide in which a halogenated naphthalin derivative represented by the following formula is added together in the preparation of polyamide by adding manganese salt to caprolactam. (단, X: 염소, 브롬, 요오드 중 일종, n: 1∼3개, Y: 알킬기, 아릴기, 카보닐기, 수류폰산기 중의 일종)(Where X is one of chlorine, bromine and iodine, n is one to three, Y is one of alkyl group, aryl group, carbonyl group, and hydrofluoric acid group) 제1항에서 상기 할로겐화 나프탈린 유도체의 첨가량이 카프로락탐 대비 0.01∼0.5중량%인 것을 특징으로 하는 내열성 폴리아미드의 제조방법.The method for producing a heat resistant polyamide according to claim 1, wherein the amount of the halogenated naphthalin derivative added is 0.01 to 0.5% by weight relative to caprolactam. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
