Abstract
Procedimiento para la preparación de materiales sintéticos de poliuretano, caracterizado porque poliisocianatos, compuestos de alto peso molecular conteniendo como mínimo dos átomos de hidrógeno reactivos con respecto a los isocianatos y, en caso dado, agentes prolongadores de cadena se hacen reaccionar en presencia de una combinación de catalizador de 1 mol de un compuesto metálico de fórmula general Me Xn Ym, donde Me significa un metal (n+m)-valente, preferentemente del grupo secundario I., II., VII u VIII o del grupo principal IV, del sistema periódico de los elementos, X significa un resto hidrocarburo alifático con 1 a 18 átomos de carbono, un resto hidrocarburo aromático con 6 a 10 átomos de carbono o un resto hidrocarburo aralifático con 7 a 15 átomos de carbono, Y significa un resto carboxilato alifático, en caso dado llevando enlaces dobles olefinicos y/o grupos hidroxilo alcoholicos, con 2 a 18 átomos de carbono, o un resto enolato con 5 a 18 átomos de carbono, n representa un número entero entre 0 y 2 y m representa un número entero entre o y 4, bajo la limitación de que la suma (n+m) sea de 2 a 4.
