Abstract

Esta invencion se refiere a un procedimiento de produccion in situ de una mezcla de un polieter monoalcohol y un polieter polialcohol. Este procedimiento comprende la introduccion de un monoalcohol (Si) y un catalizador cianuro metalico doble (DMC) en una vasija de reaccion, la introduccion como alimentacion en la vasija de una mezcla de epoxido y dejar que el epoxido reaccione con el iniciador inicial y continue la polimerizacion por alimentacion del epoxido hasta que el peso equivalente del monoalcohol alcanza el nivel deseado, anadir entonces de forma continua un iniciador polifuncional (Sc) a la vasija de reaccion mientras se continua la alimentacion de la mezcla de epoxido, completando la adicion del iniciador, y dejando que la mezcla continue polimerizandose hasta que la mezcla resultante de polieter monoalcohol y polieter polialcohol tiene un peso equivalente medio de aproximadamente 350 a aproximadamente 750, y una funcionalidad media de aproximadamente 2 a aproximadamente 4. Las mezclas polimerizadas in situ de un polieter monoalcohol y un polieter polialcohol forman parte tambien de la presente invencion. La presente invencion se refiere asimismo a un procedimiento para la produccion de espumas viscoelasticas. Este procedimiento comprende la reaccion de un componente poliisocianato con un componente reactivo a isocianato, en presencia de aditivos, donde el componente reactivo a isocianato constituye al menos 50% en peso de la mezcla polimerizada in situ de un polieter monoalcohol y un polieter polialcohol como se ha definido antes.
