Title:
NEW AZOAMIDE COMPOUND
Document Type and Number:
Japanese Patent JP3937496
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compound having high-temperature activity, excellent in solubility to an organic solvent, having high melting point and high capability of polymerization, and useful as a polymerization initiator.
SOLUTION: This compound is an azoamide compound of formula I (R1 and R2 are each an independent lower alkyl; R3 is ≥2C saturated alkyl) and e.g. 2,2'-azobis(N-cyclohexyl-2-methylpropionamide) is exemplified. The compound of formula I is obtained by reacting an azodicarboxylate compound of formula II (R4 is a lower alkyl) with an amine compound of formula III in a suitable solvent or without any solvent and in the presence of an alkaline organic metal compound. For instance, the compound in the concrete example is obtained by mixing cyclohexylamine with dimethyl 2,2'-azobis(2-methylpropionate) and reacting, after dropping a mathanol solution containing 28% sodium methoxide under stirring.
