    摘要: These low viscosity polyesters and their products, such as urethanes produced with organic polyisocyanate(s) alone or plus a reactive diluent, such as a glycol or polyester glycols are uniquely useful for coatings, liquid coatings and as an adhesive for films and rubbers. These copolyesters are highly viscous at 24.4.degree. C. but at 40.degree. to 60.degree. C. they are thin enough to be intimately mixed with reactants such as an organic polyisocyanate or epoxy resin and diluents without need to use solvents which pollute the atmosphere.

    摘要: A polyester urethane fuel cell having at least one layer of a reaction product of an organic polyisocyanate and a mixed polyester and a curative. In the preferred embodiment the fuel cell has a barrier layer composed of a polyester urethane formed from reacting bis(4-cyclohexyl isocyanate) with 10 to 90 mol percent of polyhexamethylene ortho phthalate and 90 to 10 mol percent of a polycaprolactane and curative. The mixed polyesters are either a blend or co-condensation product of a monomeric polyol of less than 5 carbon atoms with an aromatic dicarboxylic acid and an aliphatic dicarboxylic acid.

    摘要: A solid industrial polyurethane tire and a wheel assembly comprised of such a tire adhered to a rigid central core, or hub. The hub is generally adaptable to fit onto an axle of an industrial vehicle. Said polyurethane tire is prepared by reacting 2,2'-dithiodianiline with a prepolymer of selected diisocyanates and selected polymeric polyester and polyether polyols and their mixtures.

    摘要: Shock absorbing unit which comprises a shaped resilient polyurethane composition characterized by being able to withstand compressive cycling and particularly being characterized by retaining a high degree of rebound after a multitude of compressive cycling cycles. The unit is suitable for use in a railroad draft gear. Such polyurethane composition for said shock absorbing unit is prepared by reacting specifically selected polyols with a corresponding balance of 1,5-naphthalene diisocyanates in combination with mixtures of certain polymeric polyols with a manipulation of their molecular weights.
