ABSTRACT:
The resistance to degradation on exposure to high temperatures, water and organic liquids of a polyurethane prepared by reacting a tetrahydrofuran/alkylene oxide polymerizate, an organic polyisocyanate and a chain extender is significantly improved by using a tetrahydrofuran/alkylene oxide polymerizate which contains no more than about 3%, by weight, of oligomeric cyclic ethers.
