New type of polymer additives
Thread Content
4,4’-Azobis(4-cyanopentanoic acid) and 4,4’-Azobis(4-cyanopentanol) are used as polymerization initiators for the polymerization of common vinyl monomers. It can also be used in copolymers of vinyl compounds. It is a very effective free radical. It has been used on a large scale abroad for 10 years, while research on it has only recently begun in China. Those who are interested, let’s discuss it together.
Azo compounds: currently, azobisisobutyronitrile is used quite frequently
Yes, azobisisobutyronitrile (AIBN) is used widely because it is inexpensive. But there is still a difference between the two: AIBN is oil-soluble, while the latter two are water-soluble. Their uses are different. Moreover, AIBN has a low decomposition rate and is considered a low-activity initiator.
The commonly used azo compound initiator is azobisisobutyronitrile (AIBN). Its advantages include uniform decomposition, formation of only one type of free radical, no side reactions, stability, safety, and non-toxicity
Are the decomposition by-products of AIBN non-toxic?
