Producing method of polyurethane resin, polyurethane resin, and molded article |
| abstract |
A method for producing a polyurethane resin includes a reaction step of obtaining a primary product by reacting a polyisocyanate component containing a bis(isocyanatomethyl)cyclohexane with a polyol component containing a low molecular weight polyol having a number average molecular weight of 400 or less and a high molecular weight polyol having an average molecular weight of 2500 or more and 4000 or less under the presence of a bismuth catalyst, and a heat treatment step of heat treating the primary product to obtain a polyurethane resin. The bismuth catalyst content in the polyurethane resin is 0.1 ppm or more and 1000 ppm or less, and the heat treatment conditions in the heat treatment step are 50° C. or more and 100° C. or less and three days or more and ten days or less. |
