Abstract
Poly(2,6-dimethyl-1,4-phenylene ether) (PPE) was synthesized by oxidative polymerization using various Cu(I)-amine catalyst system. The effects of catalyst/monomer ratio, different amine ligand, and the content of 2,4,6-trimethylphenol (TMP) additive on the polymer yield and molecular weight were investigated by using gel permeation chromatography. The catalytic activity of various Cu-amine systems on the 2,6-dimethylphenol (DMP) polymerization was monitored and compared each other through oxygen-uptake experiment. In addition, the effect of catalyst removal using aqueous EDTA on the thermal stability of the prepared polymer was elucidated by thermogravimetric analysis.

Copper(I) chloride와 아민 계열의 리간드와의 Cu-amine complex 촉매를 사용한 단량체 2,6-dimethlyphenol (DMP)의 산화중합을 통하여 poly(2,6-dimethyl-1,4-phenylene ether)(PPE)를 제조하였다. 중합반응에 있어서 DMP와 촉매의 비율, 다양한 리간드 및 첨가제로서 2,4,6-trimethylphenol(TMP)의 함량 등 여러 반응 변수들의 영향을 분자량측정, 열분석, 및 광학적 특성분석을 통해 조사하였다. DMP의 산화중합에 사용된 다양한 Cu-amine 촉매 system의 중합활성을 비교하기 위하여 oxygen-uptake 실험을 실시하였다. 또한 제조된 PPE의 EDTA 수용액을 사용한 정제 방법을 통하여 잔류촉매 제거가 PPE의 열 안정성에 미치는 효과를 TGA를 통해 확인하였다.

Keywords: poly(phenylene ether); oxidative coupling; oxygen-uptake; EDTA; thermal property.
