Participants

Reaction Steps

In a 50-mL three-neck round-bottom flask equipped with a thermometer, a condenser and a nitrogen inlet, was placed a solution of 4 g of 2-(4-trimethylsilyloxymethyl-phenoxy)ethyl vinyl ether (prepared as in Example 1) and 1.47 g of maleic anhydride in 25.1 mL of 1,2-dichloroethane. The system was purged with nitrogen for 30 minutes. Then 96 mg VAZO®67, and 0.24 mL butanethiol were added under nitrogen. The polymerization was carried out at 60.C for twenty-four hours or longer until complete monomer conversion. The copolymer was isolated by precipitation in hexane.
