Abstract |
Abstract Wet polyurethane resin was synthesized by using polytrimethylene ether glycol
prepared from 1,3-propanediol produced by fermentation from corn sugar as bio polyol
and polyether-polyol(PTMG). Physical properties and cell characteristics by wet coagulation were investigated using the synthesized wet polyurethane resin. The tensile strength
of wet polyurethane resin decreased with increasing content of bio polyol as copolymer
polyol, but it tended to increase elongation at break and tear strength. As a result of thermal characteristic analysis, it was found that the glass transition temperature was slightly
increased as the content of bio polyol increased. As a result of comparing the cell characteristics by the wet coagulation method, it was found that the shape of the cell was
good when the ether polyol and the bio polyol were used alone. |
