Abstract
Waterborne polyurethane(PU) microgel dispersions were synthesized with different mole ratio of polytetramethylene glycol(PTMG) to dimethylol propionic acid(DMPA). Particle size distribution, thermal and mechanical properties of the PU microgels were investigated. Particle size of the microgels was distributed in the range of
폴리테트라메틸렌글리콜(PTMG) 및 디메틸올프로피온산(DMPA)의 몰비를 변화시키며 수분산성 폴리우레탄 마이크로겔 분산체를 합성하였다. 합성한 폴리우레탄 마이크로겔의 입도분포, 열적 및 기계적특성을 실험하였다. 마이크로겔의 입자크기는
