POLYURETHANE |
| 摘要 |
A polybutadiene having a hydroxyl group at a terminal end thereof is reacted with a lactone compound such as an ε-caprolactone to obtain a polymer polyol represented by formula (I): HO—X1—Y—X2—OH (wherein X1 and X2 each independently represents a polyester component and Y represents a polybutadiene component), the polymer polyol is reacted with an unsymmetric diisocyanate to obtain a urethane prepolymer, and then the urethane prepolymer is reacted with a chain extender to obtain a polyurethane. |
