  • Two-component polyurethane adhesive
    Patent number: 5041517
    Abstract: A polyol is reacted with a polyisocyanate prepolymer to make a polyurethane. The polyol is the reaction product of trimethylol propane with ethylene oxide (1:3 molar). The polyisocyanate prepolymer is the reaction product of poly(ethylene adipate) with MDI. The novel polyurethane is stable in both aliphatic and aromatic hydrocarbons and is especially useful in bonding together laminates of nylon-supported permeable membranes. The laminates are used in modules for separation of hydrocarbon-containing gases.
