Abstract
Procedimiento para la obtención de oligo y poliuretanos lineales mediante reacción de 1 mol de a) diisocianatos con 1 mol de b) compuestos con dos grupos reactivos con isocianatos, caracterizado porque los grupos funcionales de a) y/o b) muestran frente a los grupos funcionales de otro componente reactivo reactividades diferentes y las condiciones de reacción se seleccionan de tal manera, que reaccionan entre sí respectivamente tan solo determinados grupos funcionales de a) y b), y el compuesto así obtenido, que contiene tanto un grupo de isocianato libre, como también un grupo libre y reactivo con grupos isocianato, reacciona de manera intermolecular para dar un oligo - o poliuretano.
