Versuchsvorschrift

To 795.4 g of laurylmethacrylate is added 4.64 g of glacial acrylic acid and 800 g of liquid hydrocarbon sold commercially as Isopar® M by Exxon. Then 0.8 g of 2,2'-azobis(2,4-dimethylvaleronitrile) which is sold commercially as Vazo® 52 by E. I. duPont de Nemours Corporation is added. The solution is agitated, purged with nitrogen for 1 hour and then heated to 50° C. After 12 hours of heating, the temperature of the thickened solution is increased to 60° C. and held there for 2 hours. It is then cooled and mixed with another 800 g of the aforementioned liquid hydrocarbon to give a 33 percent polymer solution.
