Abstract: A process of making a polyurethane condom which comprises providing an organic solvent solution of a polyurethane, a single dipping of a condom form or mold into the polyurethane solution, raising the form from solution and allowing the resultant deposited film to cure at elevated temperatures, thereby forming the condom.

Abstract: A soft, low modulus, non-crystalline segmented polyurethane characterized by a 100% modulus less than about 250 psi, initial tensile set less than about 30% and tensile strength of about 3500 to 6500 psi obtained by balancing the percent hard segment and the degree of cross-linking within the ranges 14 to 25% hard segment and 5,000 to 30,000 molecular weight per cross-link in a segmented polyurethane; and a flexible glove for use by surgeons and others which is easily donned and comfortable on the hand, wherein the glove forming material consists essentially of the aforesaid polyurethane.

Abstract: A powder coating process for producing soft, flexible polyurethane films particularly in the form of a surgical glove, wherein low melting crystalline prepolymer particles are powder coated and cured to an essentially non-crystalline film.

Abstract: A crystalline grindable end-blocked prepolymer useful in providing a polyurethane elastomer having a 100% modulus less than approximately 250 psi, tensile of 3500 to 6500 psi, and less than 30% initial tensile set, said prepolymer being the product of reacting an organic polyisocyanate, a long chain crystalline diol having an average molecular weight of approximately 500 to 5000, a polyhydroxy cross-linking agent, and an end-blocking agent.
