摘要： Tough, heat-formable sheet material and mouldable articles produced therefrom comprising a high-molecular weight synthetic resin as stiffening component wherein the stiffening component is a low-melting, highly-crystalline polyesterurethane formed by reacting polyester chains with isocyanate to obtain sufficient molecular weight to give desired properties.Products are especially suitable for use in shoe counters and can be formulated to combined desired mechanical properties with predetermined set-up times during which mouldability is retained to enable several shoe-making operations to be carried out without the need for further heating.

摘要： Heat curable compositions, particularly solvent-based adhesive compositions suitable for use e.g. in flocking processes, are described and claimed. Known heat curable compositions require a relatively high temperature for cure. A one part non-toxic storage stable composition is provided which is cured by heat and comprises a polyurethane prepolymer formed from the reaction between a first NCO terminated prepolymer, an oxime blocking agent and a trifunctional primary amino compound used in a substantially stoichiometric amount to the amount of isocyanate groups of the first prepolymer available for reaction. The quantity of blocking agent is so chosen that statistically only one functional group of the triamine is reacted with the NCO groups of the first prepolymer available for reaction leaving two amine groups available for reaction with isocyanate groups of the prepolymer when they are unblocked by heating.

摘要： A polyurethane composition, e.g. suitable for use in solution as an adhesive or primer for bonding tread members to shoes. The polyurethane is made from reactants comprising polyisocyanate, hydroxyl terminated polyol, difunctional reaction product of methyl methacrylate and a substituted alkene (e.g. but-2-ene 1.4 diol) having two chemical groups available for reaction with isocyanate, and chain extender.
