Procedure

Phenyl vinyl ether (88.1 g, 0.7341 moles) (prepared as in Example 1) and maleic anhydride (71.9 g, 0.7341 moles) were dissolved in 1224 mL of 1,2-dichloroethane. The solution was placed in a 2-liter three-neck round-bottom flask equipped with a thermometer, a condenser, and nitrogen inlet, and it was purged with nitrogen for half an hour. Then VAZO® (4.7 g, 0.02447 moles) (a radical intiator supplied by DuPont) and butanethiol (11.8 mL, 0.1101 moles) were added under nitrogen. The polymerization was carried out at 60° C. for about 24 hours to complete monomer conversion. The polymer was isolated by precipitation in hexane.
