Process for the manufacture of an adhesive, characterized in that it comprises the reaction of an aromatic diol with the available -NCO groups of an isocyanate-terminated polyurethane, coming from the reaction of a polyalkylene ether glycol, in which the alkylene group has from 1 to 4 carbon atoms, with an aromatic polyisocyanate, in an approximate molar ratio of 1: 1.2 to 1: 4 obtaining a substantially linear thermoplastic resinous reaction product that melts at about 60º to 200º C and hardens to a high tenacity state at temperatures not lower than 50ºC.
