Abstract

El objeto de esta invención es un método para fabricar elastómeros-PU compactos o celulares, preferentemente microcelulares por conversión de: a)compuestos polihidroxilo de alto peso molecular y, en caso necesario, b) medios prolongadores deca dena y/o reticulantes de bajo peso molecular con c)poliisocianatos orgánicos en presencia o en ausencia de:d) catalizadores, e) expansores, f) aditivos, usando como poliisocianato orgánico, 3,3-dimetil-difenil-4,4-diisocianato y por lo menosun di isocianato aromático adicional, seleccionado del grupo formado por diisocianato de toluileno, de difenilmetano,de 1,2-difeniletano y de fenileno y/o por lo menos un diisocianato alifático con 4 a 12 átomos de carbono y/o por lo menos undiisocia nato cicloalifáticocon 6 a 18 átomos de carbono. De acuerdo con una forma de realización preferida del método, los elastómeros-PU se obtienen por el método deprepolímero, donde a partir del compuesto polihidroxilo de alto pesomolecular (b ) y por lo menos un diisocianato aromático, seleccionado del grupo formadopor diisocianato de toluideno (TDI), MDI, diisocianato de 1,2-difeniletano (DIBDI) y diisocianato de fenileno (PDI) y preferentemente 4,4-MDIy/odiisocianato de 1,6-hexame tileno (HDI) y/o 1-isocianato-3,3,5-trimetil-5- isocianatometil-ciclohexano (IPDI) se obtiene ventajosamente un producto depoliadición que contiene grupos uretano e isocianato, el que puede ser convertidocon TODI, que puede hacerse re accionar en una etapa o por porcionescon el producto de poliadición, en el prepolímero que contiene grupos isocianato. Los elastómeros-PU pueden obtenerse a partir de tales prepolímerosque contienen gruposisocianato, por conversión con agu a o mezclas de agua y en caso necesario medios prolongadores de cadena o reticulantes de bajo peso
