Polyurethane-urea elastomers based on propylene oxide-tetrahydrofuran copolymers |
| abstract |
A polyurethane-urea elastomer is prepared by reacting a copolymer of propylene oxide and tetrahydrofuran having hydroxyl end groups with an organic polyisocyanate and the isocyanate-terminated polymer is then reacted with an aromatic diamine in either bulk or solution process. |
