Study on the Hydrophilicity of Modified Polyester

초록

Dimethyl terephthalate, ethylene glycol, polyethylene glycol 및 계면활성제인 dodecylbenzene sulfonate를 반응시켜 개질시킨 poly(ethylene terephthalate) 중합체를 합성하였다. 이들의 점성도, 색상변화, 접촉각측정법으로 친수성 등을 살펴보았다.

The modified poly(ethylene terephthalate) (PET) was synthesized by copolymerizing dimethyl terephthalate with ethylene glycol, polyethyleneglycol, and dodecylbenzene sulfonate as a surfactant. After characterization of viscosity, color, and contant angle, hydrophilic characteristics of the modified PET depending on additives was discussed.

Keywords:Poly(ethylene terephthalate);Hydrophilicity;Dodecylbenzene Sulfonate;Polyethylene Glycol
