Procedure

To 15 g. of styrene placed in a tube is added 5 g. of the product obtained on Example V. 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 sixteen hours at +50° C. and tested by the demixing test. (4)-(5).
