  • Flexible breathable polyurethane coatings and films, and the prepolymers from which they are made
    Patent number: 4942214
    Abstract: The invention relates to flexible breathable polyurethane coatings and films and to the prepolymers from which they are formed. These prepolymers are isocyanate-capped poly (alkylene oxide) glycol polyurethanes with low viscosities and low freezing points. The difunctional nature of the random copolymers of ethylene oxide and prepylene oxide added to simple diols provide the low viscosity and low freezing points; high levels of ethylene oxide in the polyol provides the breathability.
