Emulsion Blends of Polyurethane Ionomers from Ester and Ether Type Polyols

초록

Soft segment가 각각 ester 및 ether형 polyol로된 2종의 polyurethane(PU) ionomer를 emulsion 블렌딩하여, 블렌드의 분산점도, 및 emulsion cast film의 접촉각, 기계적 특성을 조성의 함수로 측정하였다. 블렌드의 기계물성은 혼합법칙으로부터 심한 scattering이나, negative deviation을 보였으며, 이는 ester 및 ether형 polyol간의 상용성의 결여에 기인하는 것으로 보았다. 접촉각 측정 결과로부터 유화입경이 작은 PPG PU 입자가 주로 도막표면층을 형성하는 것을 확인할 수 있었다.

Two types of polyurethane(PU) ionomer dispersion having different type of soft segment, viz. Poly (tetramethylene adipate) glycol(PTAd), and polypropylene glycol(PPG) were emulsion blended. Viscosity of emulsion blend, mechanical, and surface properties of the emulsion cast films were determined as a function of blend composition. Mechanical properties showed a large scatter of data or negative deviation from the additivity rule, and this was attributed to the incompatibility of soft segments. Contact angle measurement indicated that air facing surface of emulsion cast film contained more of PPG PU, due probably to its smaller particle diameter compared to PTAd PU.
