Free radical polymerization of 2,3-bis(cyanopropyl)-1,3-butadiene
The bulk free radical polymerization of 2,3-bis(cyanopropyl)-1-3-butadiene (III) produces a crosslinked, insoluble polymer after six hours. Uncrosslinked homopolymer shows exclusively 1,4 microstructure and is resistant to a wide range of common organic solvents. Copolymerization of III with I, and III with styrene produced dicyano-functionalized SBR and an all diene based cyano content than NBR while maintaining flexibility of the polymers.
