Applications
VA-061 is the free base of VA-044 and VA-046B, which are water-soluble azo polymerization initiators. By forming salts with different organic acids, the product dissolves in water, creating a highly effective initiator for polymerization of water-soluble vinyl monomers.
- Non-nitrile azo initiator
- Soluble in acidic aqueous solution, the potential for aqueous polymerization of non-halogen using organic acid like acetic acid.
- 10 Hour half-life decomposition temperature; 61℃(at about 45℃ in acidic aqueous solution)
