الإجراء التجريبي

Coagulated polymer was washed by chopping in a blender with water, twice dissolved in acetone and reprecipitated in water in a blender, then air-dried, vacuum-oven dried 3.5 hrs. at 72° C., and finally mill-dried at about 130° C. Yield: 254 g. The terpolymer produced had an inherent viscosity (chloroform, 30° C.) of 1.51 deciliters/gram and an acid content of 0.24 meq./gram (titration with aqueous sodium hydroxide), or 0.23 meq./gram (titration with alcoholic potassium hydroxide). The terpolymer had 3.3 percent monoethyl fumarate; the remainder was believed to be about equally divided between ethyl acrylate and butyl acrylate.
