| | 4,4'-Azobis(4-cyanovaleric acid) Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | 4,4′-Azobis(4-cyanovaleric acid) has been used in the preparation of polystyrene particles by polymerizing styrene in ethyl alcohol. | | 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. | | Uses | 4,4’Azobis(4-cyanovaleric Acid) is a water soluble azo initiator usded in radical polymerization process of vinyls, acylamides, styrenes as well as other polymers. | | Hazard | Toxic. | | Flammability and Explosibility | Not classified | | Biochem/physiol Actions | 4,4′-azobis(4-cyanovaleric acid) is an azo-initiator that induces lipid peroxidation of sunflower oil. | | Safety Profile | Moderately toxic byintraperitoneal route. When heated to decomposition itemits toxic vapors of NOx. |
