| titleOfInvention | Method for producing aliphatic polyester having increased molecular weight |
| abstract | An object of the present invention is to provide a method for efficiently producing a high molecular weight aliphatic polyester with high quality. In order to achieve the above object, the present invention provides a method for producing a polyurethane foam, which comprises (i) a mixing tank having a pressurized portion of a diisocyanate, wherein a number average molecular weight is 5000 or more and a terminal group is a hydroxyl group, Wherein the aliphatic polyester prepolymer is melted at a temperature not lower than the melting point and is in a liquid phase, (ii) a step of introducing an ester prepolymer into the aliphatic polyester prepolymer at a temperature higher than the melting point of the aliphatic polyester prepolymer, A step of press-fitting a diisocyanate corresponding to 1/10 to 2 equivalents from the press-fitting portion, and (iii) a step of reacting the aliphatic polyester prepolymer with a diisocyanate to produce a high molecular weight aliphatic polyester to provide. |
