Azobisisobutyronitrile → HCID 86746742, compound

Participants

Reaction Steps

A nitrogen line was connected to a two-necked flask (100 ml) provided with a cooling tube so that the air in the flask was replaced with nitrogen gas. 0.02 mole of cyanoethyl vinyl ether, which was distilled at least twice, 0.02 mole of cyanoethyl acrylate, 20 ml of acetone and 2,2'-azobisisobutyronitrile in an amount of 2mol% relative to the total amount of the monomers were then placed in the flask, followed by polymerization at 50° C. for 24 hours. The thus-formed copolymer was then reprecipitated by using methanol to obtain 4 g of an intended cyanoethyl vinyl ether-cyanoethyl acrylate copolymer. The composition ratio (cyanoethyl vinyl ether:cyanoethyl acrylate) of the copolymer was 2:3.
