摘要：
High triad isotacticity (mm = 69%) in copper/BOX mediated ATRP of MMA is achieved. The use of strong Lewis acid Yb(NTf2)(3) (1.0-8.0 mol%) and HFIP as the solvent is the key for this isotactic stereocontrol. A dilute concentration and a relatively low temperature are beneficial for further improving the isotacticity.
