AIBN: A Deep Dive into the Polymerization Catalyst

AIBN, or azobisisobutyronitrile, serves the critical role in free-radical polymerization reactions. Its substance operates the thermal initiator, experiencing breakdown upon heating by UV or radiation, producing reactive radicals. These species then start chain-growth with monomers, resulting to polymer growth. Its cleavage speed were strongly dependent on temperature, allowing this a adaptable agent for managing reaction course.
