Controlled radical polymerization with polyolefin macroinitiator: a convenient and versatile approach to polyolefin-based block and graft copolymers
TL;DR: In this paper, a new synthetic methodology of polyolefin-based block and graft copolymers with polar segments was introduced, which can be used for the synthesis of a wide range of poly-olefin based copolymer with a different content of the corresponding polar segment.

Modulation of N^N′-bidentate chelating pyridyl–pyridylidene amide ligands offers mechanistic insights into Pd-catalysed ethylene/methyl acrylate copolymerisation
Gearóid M. Ó Máille,Anna Dall'Anese,Philipp Grossenbacher,Tiziano Montini,Barbara Milani,Martin Albrecht +5 more
TL;DR: This catalyst structure is modified by inserting shielding groups either into the pyridyl fragment, or the PYA unit, or both to avoid fast β-hydrogen elimination and rationalises the formation of α,β-unsaturated esters under catalytic conditions, thus providing useful principles for optimised catalyst design.

Dual-Site Polymeric Heterogeneous α-Diimine Ni Catalysts with Tailored Spatial Distribution for Ethylene Polymerization
TL;DR: In this article , a self-supporting strategy based on nickel-catalyzed precipitation coordination polymerization of a polar monomer was used to achieve not only heterogenization of the catalysts but also spatial distribution tuning of different catalytic components in the polymeric particles.

Neutral, single-component nickel (II) polyolefin catalysts that tolerate heteroatoms
Todd Ross Younkin,Eric Connor,Jason I. Henderson,Stefan K. Friedrich,Robert H. Grubbs,Donald A. Bansleben +5 more
TL;DR: A family of catalysts has been developed whose members are tolerant of both heteroatoms and less pure starting materials, and which produce high-molecular-weight polyethylene, polymerize functionalized olefins, and require no cocatalyst.

Mechanistic Studies of the Palladium-Catalyzed Copolymerization of Ethylene and α-Olefins with Methyl Acrylate
TL;DR: In this article, the effects of reaction conditions and catalyst structure on the copolymerization reaction were rationalized, and the effect of the acrylate comonomer at the ends of branches as −CH2CH2C(O)OMe groups was analyzed.
