Zusammenfassung:To provide a novel fumaric acid diester-cinnamic acid ester-based copolymer having a high molecular weight, which is expected to maintain excellent strength or ensures excellent toughness even when formed into a film, a method for efficiently producing the copolymer, and a film using the same. The fumaric acid diester-cinnamic acid ester-based copolymer contains a fumaric acid diester residue unit, a cinnamic acid ester residue unit having an alkyl group with a carbon number of 1 to 6, and a residue unit of a polyfunctional monomer having two or more radical polymerizable functional groups.
