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