V-601
CAS : 2589-57-3
Plastics manufacturing
Photocurable
V-601 is a nitrile-free oil-soluble azo polymerization initiator which has similar level of polymerization activity as AIBN. A safer developed as alternative to AIBN, V-601 decomposition results in much less toxic byproducts. As a nitrile-free azo initiator, V-601 displays excellent solubility characteristics in organic solvents. Since the volatility of the decomposition product is higher than that of others, such a product can be removed in the process of polymer manufacturing. Being of non-nitrile type, the polymerized polymers are highly transparent, therefore, semiconductors and LCDs applications are expected.
- Non-nitrile azo initiator as an alternative to AIBN
- Freely soluble in various organic solvents, available for high solid coating.
- With equivalent polymerization activity of AIBN. Efficiency of polymerization rises in alcohol solvents
- 10 Hour half-life decomposition temperature: 66℃

Volatility of Decomposition Products
The decomposition product of V-601 is characterized by a higher volatility than that of AIBN. Also, the decomposition product of V-601 is azeotropic with water, therefore, thus can be easily removed from the post-reaction system.
- Boiling point of decomposition product of V-601: 85-90 ℃ (5 mmHg)
- Azeotropic point of decomposition product of V-601 with water: 90 ℃
