Procedure
Into a 500 ml kettle was charged 96 g of the above vinyl butyrate/maleic anhydride copolymer and 144 g of absolute ethanol. The mixture was heated to 78° C. under a blanket of nitrogen for 5 hours to yield a 50% solid solution. The reaction mixture was then cooled to 40° C. and product, vinyl butyrate/ethyl maleate copolymer (42.29% solid copolymer in ethanol) was recovered and found to have a relative viscosity of 1.24 and a specific viscosity of 0.24. This product has a K value of 30.
