Polymerization of methyl methacrylate by metallocene imido complexes and tris(pentafluorophenyl)alane
TL;DR: In this paper, the effects of the metallocene imido complex structure on the polymerization activity and polymer tacticity, the degree of polymerization control, the elementary reactions of the IMido complex with Al(C 6 F 5 ) 3 and MMA, and polymerization kinetics and mechanism were investigated.

The use of group transfer polymerization for the control of polymethacrylate molecular structure
TL;DR: The synthesis of polymethacrylates by repeated silyl Michael addition reaction (GTP)a allows one to control the molecular weight of the polymer by adjusting the monomer/initator ratio.

Recent developments in the field of star-shaped polymers
TL;DR: In this article, the authors review the different methods of preparation for star-shaped polymers and two cases of special interest are considered in greater detail: the core-first method which gives access to end-functionalized star-shape polymers, and the three-step method which leads to the so called hetero-star copolymers with rather specific properties.
