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.

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 a water soluble azo initiator usded in radical polymerization process of vinyls, acylamides, styrenes as well as other polymers.

Hazard
