10-hour Half-life Temperature by Structure

We have azo polymerization initiators fit for a large extent of 10-hour half life temperature (*). You can select an initiator fit for your purpose.

(*10-hour half-life temperature: A temperature at which the concentration (amount) of azo group becomes a half in 10 hours in the solvent.)
