| Summary: | 碩士 === 文化大學 === 應用化學系 === 85 === The experimental results show that the viscosity appears to
increase with increasing the ratio of the ratio of NCO to OH for
synthetic polyurethane resin.However, increased the ratio of
NCO/OH was found not to affect the surfancetension of synthetic
polyurethaneresin in solvent. In addition, the average partion
sizeof polyurethane resin increases with increasing the ratio of
NCO toOH, and both tensile strength and the longation of the
polyurethane film increasewith an increase of theequivalent
ratio of NCO/OH as well.
