Abstract
Polyurethane resin used to leather coat was synthesized by the addition reaction of PPG and PTMG with different mole ratios. Physical characteristics of the synthesized polyurethane resin were measured by the SEM, FT-IR and the UTM. Increasing mole ratio of PTMG having four methylene groups caused the increase of abrasion resistance and tensile strength. The elongation was decreased. As we measured the solvent(toluene) resistance of poly urethane resin, it was found the there were no effect of PTMG mole ratios on the phyhsical properties of the resin. The viscosity was increased by ratio of PTMG mole ratio.
Keywords
