Procedure

A 5-liter flask, standardly equipped, was charged with 425 grams of sucrose, and 230 grams of glycerine. The mixture was stirred and heated for 2 hours at 130°-135° C. and then 1330 grams of pentachlorophenol containing about 700 to 800 ppm of aluminum and iron compounds was added. The mixture was treated with propylene oxide until the acid number was 0.8. After heating the mixture to remove volatiles, the polyol product had the following properties.
