N2 - Amphiphilic hydroxyl functioned polyester (HFP) can be used as compatibilizers for blends of starch and resins. We developed a synthetic method for effective preparation of HFPs. Water was removed by high flow rate N 2 rather than high vacuum during polycondensation of sebacic acid with xylitol, sorbitol, or mannitol in the presence of dehydrative condensation catalyst and the product is with [η] of 27.2 mL/g, Mn of 1903, Mw of 167,693, Tg of -30.5°C, Tm of 44.0°C. Weight loss is 1.73% under 200°C. The integral distributions of molecular weight are 43.6 wt% and 63.8 wt% over 10,000 and 3000, respectively. The results indicated that higher molecular weight HFP was economically synthesized.
