Abstract

Solid-state polymerization of polycarbonate (PC) is a good way to improve the problems of existing polymerization methods. However, it requires the crystallization of PC pre-polymer as a pre-treatment step, and solvent-induced crystallization is mainly used in the pre-treatment process. In this work, the crystallinity of PC with different kinds of solvents was measured by DSC. Then, the correlation was analyzed by using the Hansen solubility parameter distance (Ra) and interaction parameter (χ). In addition, the morphology of crystals and depth of crystal region were analyzed by SEM


폴리카보네이트(PC)의 고상중합법은 기존의 중합법들의 문제를 개선하는 좋은 방법이지만, PC 프리폴리머를 결정화하는 전처리 과정을 필요로 한다. 전처리 과정에서는 용매 유도 결정화법이 주로 사용되고 있다. 본 연구에서는 다양한 용매를 이용하여 결정화한 PC의 결정화도를 DSC를 이용하여 측정하였고, Hansen 용해도 파라미터 거리(Ra)와 상호작용 파라미터(χ)를 이용하여 연관관계를 분석하였다. 또한 SEM을 이용하여 결정의 형태와 결정영역의 두께를 관찰하였다
