Abstract
Un proceso para preparar un componente de poliol homogéneo que es estable ak la separacion y que consiste de por lo menos un compuesto de peso molecular relativamente elevado que tiene por lo menos dos átomos de hidrogeno reactivos y, alargadores de cadena y/o reticuladores de bajo peso molecular y, si se desea, de agentes hinchadores, catalizadores y otros auxiliares, y/o aditivos, que comprende la adicion a este componente de por lo menos una amina y por lo menos un isocianato orgánico y/o orgánico modificador; la invencion proporciona asimismo el componente de poliol correspondiente que es estable a la separacion. El uso de este componente de poliol para preparar PUR, en particular PUR compacto o espumado, se describe asimismo.
