How to select a polymerization initiator?

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.)

Organic solvent soluble type (oil-solubility)

10-hour Half-life Temperature	Azo Nitrile	Azo Ester	Azo Amidine	Azo Alkye
110°C — 80°C — 70°C — 60°C — 50°C — 30°C —	V-40（88°C） V-59（68°C） AIBN（65°C） V-65（51°C） V-70（30°C）	V-601（66°C）	VAm-110（110°C）	VR-110（110°C）

Water-soluble type (water solubility)

10-hour Half-life Temperature	Azo Nitrile	Azo Ester	Azo Amidine	Azo Imidazoline
80°C — 70°C — 60°C — 50°C — 30°C —	V-501（63°C）	VA-086（86°C）	VA-057（57°C） V-50（56°C）	VA-061（61°C） VA-044（44°C）

Free Tool for Graphing Azo Initiator Decomposition Now Available

The "Azo Polymerization Initiator Decomposition Simulator" allows you to easily visualize the decomposition of azo polymerization initiators in a graph. You can use all 15 types of azo initiators, helping you select the best initiator for your polymerization conditions and optimize your polymerization process.
