Toxicity LD50 ipr-mus: 666 mg/kg 85JCAE -,922,86
4,4'-Azobis(4-Cyanovaleric Acid) (ABCVA; ACVA) (CAS: 2638-94-0) is a water soluble azo initiator usded in radical polymerization process of vinyls, acylamides, styrenes as well as other polymers.
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. Used as initiator, Free radical initiator for polymer synthesis.
Moderately toxic byintraperitoneal route. When heated to decomposition itemits toxic vapors of NOx.
