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