Abstract

본 발명은 수평균 분자량 1,00∼3,000의 고분자량 디올화합물 0.9∼1몰과 디이소시아네이트 화합물 1.5∼2.5몰의 비율로 예비중합후 용제를 혼합하여 예비중합물의 용액을 제조하고 4종의 디아민 화합물을 일정비율로 혼합한 쇄성장제를 예비중합물의 0.65∼0.98몰% 사용하여 쇄성장시켜 방사에 유리한 점도를 만든 다음, 디아민화합물에 대하여 1∼20몰%의 모노아민화합물로 쇄정지시킨 후, 물성향상 첨가제로서 1(2(3(3,5-디-t-알킬-4-히드록시페닐)프로피오닐옥시)알킬)4-(3-)3, 디-t-알킬-4-히드록시페닐)프로피오닐옥시)2,2,6-테트라알킬피페리닌(단, 알킬은 메틸, 에틸, 프로필, 부틸 또는 펜틸기임)을 첨가하여 중합물을 얻고 이를 방사함을 특징으로 하는 탄성섬유의 제조방법에 관한 것이다.
