Procedure

A 5-liter flask, equipped with stirrer, thermometer, addition funnel and reflux condenser, was charged with 450 grams of dextrose and 191.5 grams of propylene glycol. The mixture was heated at up to 130° C. for 1 hour. Then 1330 grams of pentachlorophenol containing about 700 to 800 ppm of aluminum and iron compounds was added. Propylene oxide was then added at 117°-140° C. to effect oxypropylation until the acid number was less than 1. The mixture was then stripped of volatiles by heating for 2 hours at 80° C./1 mm. Hg. The polyol product had the following properties.
