Soft, transparent and processable thermoplastic polyurethane |
| abstract |
A soft, transparent and processable thermoplastic polyurethane resin suitable in optical application is disclosed. The resin is the product of reacting a diisocyanate, a chain extender, and a mixture of polyether polyols. The mixture of polyether polyols comprise (A) a C4 polyether polyol and (B) a C2-C3 polyether polyol where the weight ratio A/B is in the range of about 85/15 to 15/85. |
