Chemical Properties
white crystalline powder
Uses
4,4'-Azobis(4-cyanovaleric acid) is used as a free radical imitator in polymer synthesis such as polyvinyl chloride, polyacrylonitrile, polyvinyl alcohol and synthetic fibers. It is utilized for both heterogeneous and homogenous free-radical polymerizations, and as an initiator in reversible addition-fragmentation chain transfer polymerization (RAFT). It is also used as a blowing agent for plastics and elastomers.
Hazard
Toxic.
Safety Profile
Moderately toxic byintraperitoneal route. When heated to decomposition itemits toxic vapors of NOx.
