Segmented Polyurethane Ionomer에서 Polyol 종류 및 조성의 영향

Effect of Polyol Type and Composition in Segmented Polyurethane Ionomers

김태균, 김상준, 김병규

초록

환상 지방족 isocyanate인 isophorone diisocyanate(IPDI)와, poly(tetramethylene adipate) glycol(PTAd). polypropylene glycol(PPG), dimethylol propionic acid(DMPA)로부터 polyurethane(PU) ionomer를 제조, 이를 물에 분산시킴으로써 안정된 수성 PU를 제조하였으며, polyol 종류 및 조성이 유화특성 및 emulsion cast film의 열적, 기계적 성질에 미치는 영향을 검토하였다. PTAd 함량이 증가할수록 유화입경은 점근적으로 감소하였으며, 점도, soft segment T_g및 인장 거동은 증가하는 경향을 나타냈다.

Segmented polyurethane(PU) ionomers were prepared from cycloaliphatic diisocyanate, i.e. isophorone diisocyanate(IPDI), poly(tetramethylene adipate) glycol(PTAd), and polypropylene glycol(PPG) using anionic chain extender, viz. dimethylol propionic acid(DMPA). The effect of composition of soft segment on the emulsion properties, and thermal and mechanical properties of emulsion cast film were investigated using Autosizer, Brookfield Viscometer, DSC, and Instron. With more incorporation of PTAd, particle size decreased monotonically, whereas emulsion viscosity, T_g of soft segment, and tensile properties increased.
