Abstract
The present invention is a method for producing a polyfunctional polymer that contains a structural unit having a urethane bond and a polymerizable unsaturated bond in a side chain, and is characterised by including a reaction process in which a polymer (P) containing a structural unit (a) having a hydroxy group in a side chain and a monomer (M) having an isocyanate group and a polymerizable unsaturated bond are reacted in the presence of a bismuth carboxylate.
