Procedure
To a solution of 1.94 g of recrystallized maleimide (Eastman Kodak) in 20 ml of distilled cyclohexanone were added 3.69 g of decyl vinyl ether (Polysciences) which had been purified by passing through a silica adsorption column. To the mixture were then added 380 μml of dodecanethiol followed by 26 mg of azobisisobutyrlnitrile. The vessel was then sealed and deoxygenated with argon followed by placement in an oil bath where the temperature was maintained at 60° C. After six hours, the reaction mixture was poured into 500 ml of water and mixed at high speed with a blender. White precipitate was isolated by filtration. Likewise, the precipitate was mixed with 400 ml of pentene, filtered, isolated and dried overnight at 90° C. to give 4.43 g (79%) of maleimide-decyl vinyl ether copolymer.
