Abstract
A fluorine-containing highly branched polymer obtained by polymerizing a polyfunctional monomer A that has two or more radically polymerizable double bonds and all or a portion of which has a bisphenol structure, a monomer B having a fluoroalkyl group and at least one radically polymerizable double bond, within a molecule, and a monomer C having at least one ring-opening polymerizable group selected from the group including an epoxy group and an oxetanyl group, and having at least one radically polymerizable double bond, within a molecule, under the presence of a polymerization initiator D with an amount of 5% by mole to 200% by mole to the number of moles of the polyfunctional monomer A; an epoxy resin composition including the polymer; and an epoxy resin cured product obtained from the resin composition.
