N,N-chelated nickel catalysts for highly branched polyolefin elastomers: a survey [PDF]
The physical properties and end applications of polyolefin materials are defined by their chain architectures and topologies. These properties can, in part, be controlled by a judicious choice of the steric and electronic properties of the catalyst and ...
