Abstract

Procedimiento para producir una composición líquida de polímero/poliol, que es convertible, por reacción con un poliisocianato, a un producto de poliuretano, en donde el poliol de dicha composición es normalmente líquido, a la temperatura a la cual dicha composición es convertida a dicho producto de poliuretano y dicho polímero es formado in situ en dicho poliol a partir de uno o más monómeros insaturados etilenicamente polimerizables, y en donde se utiliza un primer y un segundo poliol y se proporciona una dispersión más estable de pequeñas partículas de dicho polímero en dichos polioles, caracterizado porque comprende las etapas de : polimerizar uno o más monómeros etilenicamente insaturados polimerizables, en presencia de un primer catalizador de radicales libres en dicho segundo poliol, para formar un poliol/polímero preformado que tiene una viscosidad inferior a 40.000 cps a 25ºC, mezclar una cantidad mayor de dicho primer poliol que tiene un peso molecular promedio de por lo menos aproximadamente 76 con una cantidad menor de dicho polímero /poliol preformar para formar una mezcla de los mismos y polimerizar uno o más monómeros etilenicamente insaturados polimerizables, en presencia de un segundo catalizador de radicales libres en dicha mezcla para formar dicha composición en la cual dicho polímero es formado in situ a partir de dichas dos porciones de dicho monómero o monómeros y es dispersado en dichos polioles y porque cada uno de dicho polímero/polio preformado y dicha dispersión más estable tienen una mayor estabilidad a la dispersión que el polímero/poliol que tiene la misma composición química que la de dicha dispersión más estable y está preparado de la misma manera que dicha dispersión más estable, pero en ausencia de dicho polímero/poliol preformado.
