TL;DR: In this article, the fragmentation of supports, a key issue for the polymerization of olefins via supported metallocene catalysts, was investigated by laser scanning confocal fluorescence microscopy (LSCFM).

TL;DR: In this paper, Me2Si(2MeBenzlnd)2ZrCl2/MAO supported on these nanoparticles is suitable for the homopolymerization of ethylene, resulting in excellent product morphologies and high activities.

TL;DR: In this paper, the influence of the surface of organic nanoparticles used as supports in metallocene catalysed olefin polymerization is investigated, and it is suggested that a higher amount of polypropylene oxide (PPO) chains on the support could result in a stronger network between the different nanoparticles due to the enhanced interaction of the PPO with the methylaluminoxanes so that the diffusion of the ethylene monomer to the active metal sites is hindered.

TL;DR: In this article, nano-sized latex particles are used as organic supports for metallocenes applied in olefin polymerizations, where the particles are functionalized with nucleophilic surfaces such as polyethylenoxide (PEO), polypropyleneoxide (PPO) or pyridine units allowing an immobilization of the metallocene catalysts via a noncovalent immobilization process.

TL;DR: In this paper, the authors used confocal fluorescence microscopy and laser scanning confocal optical microscopy (LSCFM) to compare different catalysts for determining the particle expansion kinetics and particle fragmentation.
