Abstract

Se producen espumas de poliuretano rígidas haciendo reaccionar a) Diisocianatos orgánicos y/o orgánicos modificados y/o poliisocianatos con b) Polioles de poliéster específicos y/o polioles de éster de poliéter que pueden prepararse mediante policondensacion de ácido dicarboxílico con alcoholes polifuncionales utilizando tereftalatos de polialquileno y, si se desea, reaccion subsecuente con oxidos de alquileno inferior más si se desea, compuestos en peso molecular relativamente elevado adicionales, que contiene por lo menos dos átomos de hidrogeno reactivos y, si se desea, c) extendedores de cadena de peso molecular bajo y/o reticuladores en presencia de d) agentes de soplado e) catalizadores y, si se desea; f) auxiliares adicionales y/o aditivos, en donde los polioles de poliéster y/o polioles deéster de poliéter se preparan en una policondensacion en etapas, en donde la primera etapa se introduce tereftalato de polialquileno en adicion a los componentes de partida en la condensacion, a medida que se comienza y/o mientras que ésta se inicia y en por lo menos una etapa adicional, se adicionan substancias catalíticamente activas. Estas espumas de poliuretano rígidas se puede usar como material aislante para los sectores de refrigeracion y de energía a gran distancia, como material de emparedado en edificacion y construccion, y como soporte y material de formacion en el sector de muebles.
