Vorschrift

One hundred twenty-five parts of butyl Cellosolve is heated to 150° C. and a monomer mix consisting of 200 parts of isobutyl methacrylate, 137.5 parts of n-butyl methacrylate, 50 parts of n-butyl acrylate, 62.5 parts of acrylic acid and 50 parts of methacryloxyethyl esters of linseed oil fatty acids and an initiator solution consisting of 1.5 parts of t-butyl perbenzoate dissolved in 10 parts of butyl Cellosolve are added to the 150° C. solvent over three hours at a constant rate. Reaction temperature is held at 150±2° C. throughout the gradual additions and for 15 minutes after the addition of an initiator chaser solution consisting of 3 parts of t-butyl perbenzoate dissolved in 10 parts of butyl Cellosolve. The polymer solution is then cooled to 100° C. and diluted with 174 parts of isopropanol.
