Maleic Anhydride → HCID 86746748, compound

Participants

Reaction Steps

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.
