POLYURETHANE COMPOSITION OBTAINED FROM A DIFUNCTIONAL PRODUCT OF THE REACTION OF METHYL METHACRYLATE WITH A SUBSTITUTED ALKENE, PRIMER OR HOT-ACTIVABLE ADHESIVE CONTAINING THIS POLYURETHANE, AND THEIR APPLICATION TO THE WELDING OF A THERMOPRUBBER SOLE

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.
