Procedure
The above amounts of diethanolamine and iodine were added to the above amount of soybean oil with stirring. The mixture was stirred for 24 hours at a temperature between about 200° F. and about 226° F. Then, the above amounts of maleic anhydride and p-toluenesulphonic acid were added with stirring. The mixture was stirred under vacuum for 20 hours at a temperature between about 200° F. and about 226° F. to give a liquid soybean oil based polyol with a hydroxyl number of 55. A reaction mixture of about 10.00 grams of the polyol and the above indicated amount of diphenylmethane diisocyanate yielded a solid soybean oil based polyurethane material.
