Sterically regulated methacrylic polymer and process for producing the same

   
   

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).

Этот вымысел обеспечивает high-molecular-weight, sterically отрегулированный метакриловый полимер имея высокое stereoregularity, узкое распределение молекулярных весов, и high molecular weight, состоя из methacrylates как блоки содержа triphenyl ETC амино групп в бортовых цепях. Sterically отрегулированный метакриловый полимер состоит из от 50 до 100 mol-%-% блока основанного на меткрилате (1) имея третичную амино группу прыгнутую до по крайней мере 2 ароматичных кольца в бортовой цепи, при котором номер-sredni1 молекулярный вес (маргаец) от 5000 до 2000000, поли коэффициент dispersity (Mw/Mn) от 1 до 1.5, и syndiotacticity метакрилового полимера 70% или больше в выражении 2-units (%rr).
