Claims (3)

ε-카프로락탐을 중합시켜서 폴리아미드를 제조함에 있어서, 점도안정제로 모노아민 및 모노카르복실산과 함께 소량의 무기할로겐염을 첨가하는 것을 특징으로 하는 일광견뢰도가 우수한 폴리아미드의 제조방법.A method for producing a polyamide having excellent daylight fastness, characterized in that a small amount of inorganic halogen salt is added together with a monoamine and a monocarboxylic acid as a viscosity stabilizer in the polymerization of the epsilon caprolactam. 제1항에 있어서, 무기할로겐염은 염화칼슘, 염화마그네슘, 염화카드뮴, 또는 염화아연 중에서 선택한 것임을 특징으로 하는 일광견뢰도가 우수한 폴리아미드의 제조방법.The method according to claim 1, wherein the inorganic halogen salt is selected from calcium chloride, magnesium chloride, cadmium chloride, or zinc chloride. 제1항에 있어서, 무기할로겐염의 첨가량이 ε-카프로락탐 1몰에 대하여 1×10-3∼1×10-2몰 임을 특징으로 하는 일광견뢰도가 우수한 폴리아미드의 제조방법.The method for producing a polyamide having excellent light fastness according to claim 1, wherein the amount of the inorganic halogen salt added is 1 × 10 −3 to 1 × 10 −2 mole with respect to 1 mole of ε-caprolactam. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
