(57) [Abstract] [Problem] Poly (meth) which can control stereoregularity arbitrarily A method for producing an acrylate ester is provided. SOLUTION: The metal compound represented by the formula (I) (Wherein, AX and Y represent monovalent ligands, and A is selected from the group consisting of aromatic hydrocarbon residues or hydrocarbon groups having 1 to 20 carbon atoms, alkoxy groups and aryloxy groups. Two or more A's may be bonded to each other via a hydrocarbon group, a Si-containing group, an O, N, S atom in the hydrocarbon residue having 1 to 20 carbon atoms, or may be bonded without a group. X is O, NR (R: H, a hydrocarbon group having 1 to 20 carbon atoms), S atom, Y is an H atom, a hydrocarbon group having 1 to 20 carbon atoms or a halogen atom. Solvent molecule, a, b, c is 0 ≦ a ≦ 4, 0 ≦ b ≦ 6, 2 ≦ a + c ≦ 4, respectively. And M represents a transition metal element of Group IIIb or Group IVb of the periodic table. ) And an organic Al compound as a polymerization initiator to polymerize (meth) acrylate. |
