초록
본 연구에서는 variable volume view cell이 장착된 상평형 장치를 사용하여 고압 상태의 다양한 용매 내에서 고분자인 Poly(methylmethacrylate) (PMMA)의 구름점(cloud point)를 측정하였다. 이때 사용된 용매는 chlorodifluoromethane (HCFC-22), dimethylether (DME), 1,1,1-trifluoroethane (HFC-143a), 1,1-difluoroethane (HFC-152a), 1,1,1,2-tetrafluoroethane (HFC-134a) 이였으며, 이들 용매에
We measured cloud points of Poly(methylmethacrylate) (PMMA) in various solvents using the high-pressure variable volume view cell apparatus. The solvents used for dissolving PMMA were chlorodifluoromethane (HCFC-22), dimethylether (DME), 1,1,1-trifluoroethane (HFC-143a), 1,1-difluoroethane (HFC-152a) and 1,1,1,2-tetrafluoroethane (HFC-134a), and the effect of
