Abstract

La presente invenzione si riferisce ad un procedimento per preparare elastomeri di poliurea o di poliuretano/poliurea mediante il trattamento a spruzzo oppure lo stampaggio ad iniezione a reazione di un miscuglio di reazione comprendente un lato A ed un lato B, in cui detto lato A comprende un poliisocianato oppure un prepolimero poliuretanico con isocianato terminale ed in cui detto lato B comprende un poliolo oppure una poliammina con l'aggiunta di un agente di prolungamento della catena, allo scopo di formare un elastomero di poliurea o di poliuretano/poliurea, detto poliolo avendo un equivalente fra circa 1.000 e circa 20.000, un peso molecolare preferito fra circa 5.000 e circa 30.000 ed un livello di insaturazione dei gruppi finali non superiore a 0,06 milliequivalenti per grammo di poliolo, detto poliolo essendo preparato impiegando un catalizzatore a base di doppio complesso di metallo cianuro, detta poliammina essendo fabbricata mediante chiusura amminica di detto poliolo con un composto contenente ammina, detto agente di prolungamento della catena essendo scelto dal gruppo comprendente un diolo ed agenti di prolungamento di catena a base di diammine aromatiche, con la condizione che detto lato B contenga almeno una certa quantità di detta poliammina oppure di detto agente di prolungamento di catena a base di diammina aromatica.
