음이온형 수분산성 공중합 폴리에스테르의 합성 및 응용 연구(I)
초록
Anionic water dispersible copolyesters were synthesized by the polycon-densation of dimethyl isophathalate/5-sodium sulfo dimethyl isophathalate with ethylene glycol/diethylene glycol. Structrual analyses such as NMR, Irm WAXD analyses were done and copolyesters were found to be correctly synthesized. Relation between feed ratio and composition ratio of EG/DEG in copolyesters was confirmed by NMR analysis. Solubility test was done to find out optimum conditon of DMS feed ration of 10 mol% in dimethyl esters. Water resistance of copolyesters decreased with the increase of DMS or DEG molar feed ratio.
