<p>A thermosetting adhesive comprising a bismaleimide compound and an isocyanate-terminated rubber polymer adapted to coreact upon heating is applied to substrate surfaces of a cured polyurethane and an uncured rubber compound. Upon heating, the adhesive crosslinks and the uncured rubber compound is preferably cured simultaneously. The adhesive is particularly useful in the fabrication of compositions by the bonding of cured polyurethane to an uncured rubber compound which becomes cured during the bonding process, such as in the construction of tires containing cured polyurethane reinforcements within uncured rubber carcasses, the retreading of tires containing polyurethane repairs, etc.</p> |
