Abstract

Un procedimiento para la obtención de cuerpos de moldeo reciclables de una manera especialmente sencilla con una densidad de 0,8 hasta 1,4 g/cm3 a partir de poliuretanos que presentan grupos urea mediante reacción en una o dos etapas de un componente poliisocianato con una funcionalidad NCO de 2,0 hasta 2,2 con un contenido en NCO del 8 al 32 en peso con un componente poliéterpoliol y con una funcionalidad de hidroxilo de 2,5 hasta 3,5 y un índice de hidroxilo de 35 a 50mg de KOH/g y diaminas aromáticas estéricamente impedidas a modo de agentes prolongadores de cadenas en presencia de catalizadores y con el empleo concomitante de agentes auxiliares y aditivos, empleándose como agentes auxiliares y aditivos poliéteraminas alifáticas con un intervalo de peso molecular de 200 a 800 y/o productos de propoxilado de etilendiamina con un intervalo del índice de hidroxilo de 200 hasta 1200 mg de KOH/g y/o productos de esterificación de 1,6-hexanodiol con ácido ricinoléico en caso dado junto a otros productos auxiliares y aditivos.
