TL;DR: In this article, a novel class of homogeneous nickel(II) catalysts, denoted as Ni(NCN)Br, is reported to mediate in the presence of activated alkyl halides, e.g., CCl4 or α-halocarbonyl compounds, and remarkably enough, poly(methyl methacrylate) (PMMA) with molecular weight up to at least 105 g/mol was synthesized in a controlled fashion.

TL;DR: In this article, the effect of carbon black (CB) on the morphology of filled polyethylene (PE)/polystyrene (PS) blends has been investigated by image analysis of optical micrographs (2D analysis) and by the selective extraction of one phase of the binary blends (3D analysis).

TL;DR: The ring-opening polymerization of lactides initiated by aluminium isopropoxide in toluene at 70°C proceeds through a "coordination-insertion" mechanism and selective rupture of the acyl oxygen bond of the monomer.

TL;DR: In this paper, the percolation threshold of carbon black in polyethylene/polystyrene heterogeneous blends can be decreased by selective localization of CB particle at the interphase rather than in one phase of the blend.

TL;DR: Thermodynamics of the polymer/solvent pair has a decisive effect on the final macroporous foams, as shown by the dependence of their porosity, density, porous morphology, and mechanical behavior on molecular weight and crystallinity of polylactide and concentration of the original solutions.
