Abstract

Un elastómero PU microcelular con propiedades dinámicas-mecánicas, mejoradas, basado en un componente isocianato esencialmente consiste en 4,4-MDI, como también en otros componentes usuales, que presenta una estructura física-química quese caracteriza porque además de tener la senal principal debajo peso molecular, que presenta una senal que consiste en uno o mas picos con una masa molar (aparente) mayor de 250.000 g/mol, medida por cromatografíade permeación de gel (GPC) en una solución de N,N-dimetilformamida con 1 por ciento de di-n-butilamina, preparada a una temperatura de 90°C, del elastómeropoliuretánico microcelular, utilizándose polimetilmetacrilato (PMMA) como patrón o standard, y que después de la adición de cloruro de litio en dichasolución, se empequenece o desaparece, y porque presenta un contenido de urea del 14 al 18% en peso. Otro objeto es un procedimiento para la preparación deun elastómero PU microcelular del tipo descripto, con mejoradas propiedades dinámicas-mecánicas, como también la utilización de los elastómeros PUmicrocelulares para la preparación de elementos amortiguadores.
