    摘要： The time when at least a monomer and a chain transfer agent are supplied in a reactor and the solution temperature in the reactor has reached a predetermined polymerization temperature is set as starting time (T0), and the time when a process to terminate the polymerization is started is set as ending time (T1). A polymerization initiator is supplied into the reactor between (T0) and just before [(T1)−(T0)/2] and between [(T1)−(T0)/2] and (T1). The total mass of the polymerization initiator supplied to the reactor between (T0) and (T1) is set as (IA), and the total mass of the polymerization initiator supplied between [(T0−T1)/2] and (T1) is set as (IB). The (IA) is set 50 to 100 mass % of the entire polymerization initiator. Using a production method in which 0.50

    摘要： Provided is a fluorine-containing macroinitiator, particularly a fluorine-containing macroinitiator that enables production of a fluorine-containing block copolymer containing a non-fluorine vinyl-based monomer having a long side chain. The fluorine-containing macroinitiator includes a polymer represented by the following formula (1) and having a number-average molecular weight of 3,000 to 100,000. In the following formula (1), R2, R3 and R4 are each a specific group, and Q is a polymer segment composed of a structural unit represented by the following formula (2). In the following formula (2), R1 is a hydrogen atom or a methyl group, Rf is a fluoroalkyl group having a specific structure, and k is an appropriate integer that is not 0.
