Abstract
The aminolysis of poly (ethylene terephthalate) (PET), which was grafted with some vinyl monomers using benzoyl peroxide as an initiator, has been investigated. The rate of degradation of back bone PET by methylamine was determined from the variation in intrinsic viscosity. The breakdown of ester linkages was assumed to occur at random along the chain. After the grafted PET had been aminolyzed, the molecular weight of branch polymer was determined, and compared with that of homopolymer. The aminolysis was found to be a good technique for the characterization of the grafted PET.
벤조일 퍼옥시드를 개시제로 하여 몇 가지 비닐단량체를 그라프트 중합시킨 폴리에틸렌테레 프탈레이트(PET)의 가아민분해를 연구하였다. 메틸아민에 의한 줄기 PET의 분해속도는 고유점도의 변화로부터 얻었다. 이 때, 에스테르 결합들의 절단은 사슬 전반에 걸쳐 무질서하게 일어난다고 가정하였다. 그라프트된 PET를 가아민 분해하여 가지 폴리머의 분자량을 측정할수 있었다. 가아민 분해 방법은 그라프트된 PET의 특성 분석에 이용될 수 있음을 알았다.
