Application
Polymer polymerization core initiator: This is the core application of 4 4 Azobis 4-cyano Valeric Acid. On the one hand, it can be used in the synthesis of conventional polymers such as polyvinyl chloride, polyacrylonitrile and polyvinyl alcohol, and can also participate in the synthesis of polymers related to optical fibers. On the other hand, 4,4′-Azobis(4-cyanovaleric acid) can be used for controlled radical polymerization. For instance, by using it as an initiator and combining it with specific chain transfer agents, the controlled polymerization of monomers such as 2-acrylamide-2-methylpropanesulfonic acid and methyl methacrylate can be achieved through the RAFT method. Polyelectrolytes with a narrow molecular weight distribution (PDI=1.08-1.17) were prepared. In addition, it can also be used to synthesize functionalized polymers, such as initiating the polymerization of styrene to obtain carboxyl-terminated polystyrene, which can be further condensed with polyethylene glycol to prepare amphiphilic block copolymers.
Other special uses: 4 4 Azobis 4-cyano Valeric Acid can be used as an initiator for the modification of bentonite and inorganic nanoparticle coated polymers; It can also act as a photosensitive agent in the near-ultraviolet region and a scavenger of oxygen in water media. In the petrochemical industry, 4,4′-Azobis(4-cyanovaleric acid) can be used to prepare shear-resistant, heat-resistant and anti-aging oil displacement polymers, which help to enhance oil recovery. It can also induce lipid peroxidation in sunflower oil and play a role in the chemical research related to oils.
