초록

AB2형 단량체인 5-aminoisophthalic acid로부터 TPP를 촉매를 이용한 축중합 반응을 통하여 고차가지구조 방향족 폴리아미드를 합성하엿다. 합성된 고차가지구조 고분자의 카복시 말단을 에탄올, 헥산올, 도데칸올로 에스테르화하여 그 특성을 연구하였다. 카복시 말단의 고차가지구조 고분자에 비해 알킬기가 차환된 고차가지구조 고분자의 용해도가 증가하였다. 또한 말단의 알킬기의 길이가 길어짐에 따라 10 wt% 무게 감소 온도가 감소하였다.

The aromatic hyperbranche dpolyamide was synthesized from 5-aminoisophthalic acid by direct polycondensation with triphenylphosphite (TPP) catalyst as a condensing agent. The modification of end-groups in the resulting hyperbranched polymer (HBP) with various alkyl alcohols were conducted. The modification of end-groups of HBP by alkyl groups resulted in an improved solubility in the THF comparing to that of the carboxylic acid-terminated aromatic HBP. Also, 10 wt% weight loss temperature decreased by increasing the length of alkyl group.

Keywords:hyperbranched polyamide;5-aminoisophthalic acid;thermal property;solubility
