Abstract

La presente invención se refiere a un proceso para la preparación de dispersiones de poliol de polímero de injerto, de baja viscosidad, estables, que contienen una cantidad mayor que aproximadamente 30 por ciento en peso de sólidos, mediante la polimerización iniciada con radical libre in situ de uno o más monómeros no saturados en la presencia de un moderador de reacción en una mezcla de poliol que contiene desde 0.001 a aproximadamente 0.3 moles de insaturación inducida por mol de poliol, caracterizado porque comprende: seleccionar como el iniciador de polimerización de radical libre, un iniciador de polimerización de radical libre que comprende el peroxi(2-etilhexanoato)de t-amilo.
