Abstract

Se pueden preparar espumas de poliuretano de alta resiliencia que exhiben poco o ningún encogimiento a partir de polioles de polioxialquileno de bajainsaturación catalizados con cianuro doblemente metálico en cantidades mayores que un 20 porcient o en peso con respecto al componente poliol total, cuandose emplean polioles aleatorios de poli(oxipropilen/oxietileno) de baja insaturación que poseen menos que un 35 por ciento en peso en la forma de unbloque solamente depolioxipropileno catalizado por catalizadores de cianuro doblemente metálico y uno o varios bloques de polioxipropileno/polioxietilenoaleatorios externos, cada uno de los cuales contiene un 2 por ciento en peso o más de porciones de oxietilenoy una insaturació n menor que 0.02 meq/g. Sedescribe también una mezcla de polioles adecuada para la preparación de la espuma de poliuretano que para la preparación de la espuma de poliuretano quecomprende uno o varios de los polioles depolioxialquileno en una c antidad entre 20% en peso o más basado en el peso de dicha mezcla de polioles y hasta80% en peso de por lo menos un poliol de alto contenido de hidroxilos primarios. También se refiere a un proceso para lapreparación de espumas depoli uretano de alta resistencia y de expansión en agua con poco o ningún encogimiento.
