To 160 g of vinyl acetate/maleic anhydride copolymer, prepared as described in Example 1A, was added 264.52 g of 1-propanol in a 500 ml kettle. This mixture was heated to 90° C. in a nitrogen atmosphere for 5 hours to effect esterification. After 5 hours, the alternating vinyl acetate/propyl maleate copolymer was obtained in a 50% solids solution. The solution was then cooled to 40° C. and product recovered. Analysis showed 46.86% solid in solution; a relative viscosity of 1.25 and a specific viscosity of 0.25, this product has a K value of 30.
