Description

This product (ABVN), also known as 2, 2 - thiazolyl (2, 4 - dimethyl) E nitrile, is the thermal decomposition of azo initiator type, melting point *6 ~ *7 ℃ (cis), *4 ~ *7 ℃ ( trans), slightly soluble in water, soluble in alcohol, benzene, ketones. ABVN is azobisisobutyronitrile (AIBN) developed on the basis of highly active initiator, it has a trigger speed, and low decomposition temperature, the trend has gradually replace the AIBN. Performance advantages: As ABVN decomposition temperature is much lower than the AIBN, at the same temperature, ABVN half-life than the decomposition of AIBN is much smaller, both ABVN faster than the decomposition of AIBN. Therefore, ABVN more suitable for the polymerization reaction temperature is low, and can shorten the response cycle, saving a lot of energy, improve labor productivity. In addition, because of its efficient cause, the amount can be greatly reduced, saving production costs. For example, in PMMA (bulk polymerization) of the production process, ABVN the amount of AIBN for *3%, if the same dosage and AIBN polymerization reaction time can be shortened by *0%. In polyvinyl alcohol (radical polymerization) of the production process, ABVN the amount of AIBN for *0% reaction time very.
