Abstract
A method for producing a highly branched polymer, with which a molecular weight can be controlled without using a polymerization inhibitor and a polymer having a controlled molecular weight can be produced safely even in a case of mass production in an industrial scale. A method for producing a highly branched polymer including polymerizing a monomer A having two or more radical polymerizable double bonds in a molecule, in the presence of a polymerization initiator B in an amount of 5% by mol to 200% by mol with respect to 1 mol of the monomer A at a temperature 20° C. higher than a 10-hour half-life temperature of the polymerization initiator B or higher.
