Reaktionsschritte

A mixture of monomeric methyl-2-cyanoacrylate (16.0 g.), styrene (4.0 g), and 500 ml petroleum ether having a boiling range of 80° - 110°C. was added to a 1000 ml., 4-neck flask. The mixture was stirred and flushed with dry nitrogen while the temperature was slowly raised to 65°C. to complete the dissolution process. After this azobis-(isobutyronitrile) (0.10 g) was added and stirring ceased. The reaction mixture was held at 80°C. for 2 to 3 hours and the copolymer precipitated. The precipitate was stirred to suspend the precipitated copolymer and then the copolymer was collected on a suction funnel and dried at 60°C. under vacuum. The dried copolymer had a reduced viscosity of 1.48 (0.4 g in 100 ml. dimethyl formamide).
