PROBLEM TO BE SOLVED: To provide a new fumaric acid diester-cinnamic acid ester-based copolymer having a high-molecular weight which is expected to maintain excellent strength when formed as a film and to provide a method for efficiently producing the same.SOLUTION: There is provided a fumaric acid diester-cinnamic acid ester-based copolymer which contains a fumaric acid diester residue unit, a cinnamic acid ester residue unit having an alkyl group having 1 to 6 carbon atoms and a residue unit of a polyfunctional monomer having two or more radical polymerizable functional groups. |
