Graft polymerization of styrene monomer initiated by azobis(4-cyanovaleric acid…
WebTo initiate the polymerization, initiators need to be added to the system containing vinyl monomers and cross-linkers to generate free radicals. Typical initiators include ammonium persulfate (APS) [74], azobisisobutyronitrile (AIBN) and 4,4′-azobis (4-cyanovaleric acid) (ACVA) [75], etc. WebIniper azo-initiators are symmetrical azonitrile compounds decomposing thermally by cleavage of the two carbon–nitrogen bonds to form two alkyl radicals and a nitrogen molecule. The resulting tert-alkyl radicals are … how to set up axis camera
