초록

본 연구는 초임계 용매인 $CO_2$, 에틸렌, 프로판, 부탄, 프로필렌, 1-부텐, 디메틸에테르 및 $CHClF_2$내에서 poly(propyl acrylate)와 poly(propyl methacrylate) 용액과의 고압 상거동을 측정하였다. 초임계 용매들과 poly(propyl acrylate) 및 poly(propyl methacrylate)간의 상거동 측정 범위는 온도 $23-186^{\circ}C$와 압력 2,400 bar까지 실험하여 나타내었다. poly(propyl acrylate)-$CO_2$ 혼합물은 약 2,070 bar 이내에서, poly(propyl acrylate)-에틸렌계는 1,400 bar 이하에서, poly(propyl acrylate)-프로판계는 1,880 bar 이하에서, poly(propyl acrylate)-프로필렌계는 450 bar 이하에서, poly(propyl acrylate)-부탄계는 2,200 bar이하에서, poly(propyl acrylate)-1-부텐계는 250 bar 이하에서, poly(propyl acrylate)-디메틸에테르계는 150 bar 이하에서 각각 용해되었으며, 이때 온도범위는 $23-175^{\circ}C$이였다. poly(propyl methacrylate)-$CO_2$ 혼합물은 2,900 bar 및 온도 $240^{\circ}C$에서도 용해되지 않았다. poly(propyl methacrylate)-프로판계는 약 2,390 bar이하에서, poly(propyl methacrylate)-부탄계에 대해서는 2,100 bar이하에서, poly(propyl methacrylate)-프로필렌계에 대해서는 570 bar 이하에서 poly(propyl methacrylate)-1-부텐계는 310 bar 이하에서, poly(propyl methacrylate)-$CHClF_2$계에 대해서는 300 bar 이하에서, 그리고 poly(propyl methacrylate)-디메틸에테르계에 대해서는 170 bar 이하에서 각각 용해되었으며, 이때 온도범위는 $40-186^{\circ}C$ 사이였다. 또한 이성분 poly(propyl acrylate)-$CO_2$와 poly(propyl acrylate)-디메틸에테르계의 상거동 사이에 디메틸에테르를 공용매로 사용하여 5, 15 및 50 wt% 첨가하여 구름점의 거동을 상임계용액온도 영역에서 하임계용액온도 영역까지 나타내었다.

High pressure phase behavior data for poly(propyl acrylate) and poly(propyl methacrylate) with supercritical $CO_2$, ethylene, propane, butane, propylene, 1-butene, dimethyl ether, and $CHClF_2$ were measured in the temperature range from $23^{\circ}C$ to $186^{\circ}C$ and at pressures up to 2,400 bar. The cloud point were obtained at dissolved pressure below 2,070, 1,400, 1,880, 450, 2,200, 250, and 150 bar for poly(propyl acrylate) in supercritical $CO_2$, ethylene, propane, propylene, butane, 1-buthen, and dimethyl ether, respectively. The temperature range is $23-175^{\circ}C$. The poly(propyl methacrylate) does not dissolve in $CO_2$ at temperature of $240^{\circ}C$ and pressure 2,900 bar. The poly(propyl methacrylate)-propane, poly(propyl methacrylate)-butane, poly(propyl methacrylate)-propylene, poly(propyl methacrylate)-1-butene, and poly(propyl methacrylate)-$CHClF_2$ systems were dissolved at the pressures less than 2,390 bar, below 2,100 bar, below 570 bar, below 310 bar, below 300 bar, and below 170 bar, respectively. The temperature range shows from 40 to $186^{\circ}C$. The phase behavior of between binary poly(propyl acrylate)-$CO_2$ and poly(propyl acrylate)-dimethyl ether system were measured from upper critical solution temperature region to lower critical solution temperature region with added dimethyl ether concentrations of 5, 15 and 50 wt%.
