| 摘要 |
This invention provides a high-molecular-weight, sterically regulated methacrylic polymer having high stereoregularity, a narrow distribution of molecular weights, and a high molecular weight, comprising methacrylates as units containing triphenyl amino groups etc. in side chains. The sterically regulated methacrylic polymer comprises 50 to 100 mol-% unit based on methacrylate (1) having a tertiary amino group bound to at least two aromatic rings in a side chain, wherein the number-average molecular weight (Mn) is 5000 to 2000000, the poly dispersity coefficient (Mw/Mn) is 1 to 1.5, and the syndiotacticity of the methacrylic polymer is 70% or more in 2-units expression (% rr).
