Macroazo compounds, which comprise a repeating unit composed of a moiety of the formula (a), a moiety of the formula (b) and a moiety of the formula (c) Image wherein X, E, Z and T are independently a lower alkylene group, R1, R2, R3 and R4 are independently a lower alkyl group or a cyano group, R5, R6, R7 and R8 are independently a lower alkyl group or an aryl group, and m and n are independently a positive integer, those moieties being bound with one another through a carboxylic acid ester linkage or a carboxylic acid amido linkage, make it possible, for instance, in a case of using the compound as a polymerization initiator, to produce easily and at high efficiency a block polymer containing both polyorganosiloxane units and polyoxyalkylene units in its molecule.
