  • Patent number: 6258869
    Abstract: Polyols useful for preparing foamed polyurethane systems are produced by reacting a feed stock of agricultural origin with a multifunctional hydroxyl component in the presence of a catalytically effective amount of a catalyst suitable to polymerize the agricultural feed stock. The reaction may further include a di basic acid, such as phthalic or adipic acid, or a diol, DEG, or PEG. The resultant polyol is then purified and blended with other ingredients to produce a formulated polyol suitable for specific polyurethane foam systems. The polyols produced in accordance with the method are also described.
