A 15-gallon stainless steel reactor was charged with 15.49 kg of propoxylated allyl alcohol (available from Arco Chemical Company of New Town Square, Pa.) and 9.88 kg of maleic anhydride (available from Huntsman Specialty Chemical). For stability, 2.53 g (100 ppm) of HQ was added to the reactor. The mixture was heated under a nitrogen atmosphere at 250-300° F. (121-149° C.) for four hours. The reaction endpoint was when the acid value reached a level of 263.4 Meq KOH/g of alkyd and no more maleic anhydride was observed by infrared spectroscopy. The viscosity of this product ranges from 100-130 cps at a temperature of 200° F. (93° C.) as measured by an ICI cone-and-plate viscometer. This material may be used directly as a film former.
