Procedure

To 15g. of styrene placed in a tube is added 5g. of the product obtained in Example III. The tube is sealed under a nitrogen atmosphere and heated for seven hours at +70°C to +100°C. The polymer obtained from the reaction is dissolved in benzene and precipitated with odorless mineral spirit. The polymer is dried in a vacuum oven for 16 hours at +50°C and tested by the demixing test. (4)-(5).
