Description

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
