093ChemInform Abstract Due to the insolubility of the title compound (III) in suitable solvents, its conversion to the corresponding acid chloride is only possible with PCl5/AcCl (see scheme). Reaction of this chloride with conc. ammonia gives the amide (V).

This paper deals with a kinetic study of methyl methacrylate polymerization in the presence of a bifunctional initiator, viz. N,N'-bis[(Crbu tylazo-4-cyanovaleryI)oxyethyl]-azo-bis-formamide.The activation energy of the first step in thermal decomposition has been determined (Ed = 74.5 kJ/mol) using the gas chromatographic method. A dilatometric study led to the reaction order with respect to the initiator, as well as the overall activation energy of polymerization ( E = 78.5 kJ/mol).
