Front Cover : In article number 1900259 by Carlos Guerrero‐Sánchez, Odilia Pérez‐Camacho, and co‐workers, self‐assembled structures based on poly(alkylmethacrylates) (PnAMAs) and methylaluminoxane (MAO) are used to stabilize metallocene catalytic systems and to control the morphology of high density polyethylene (HDPE) in ethylene polymerizations. Characterizations by dynamic light scattering (DLS), transmission electron microscopy (TEM), and bulk density of HDPE, confirmed that poly(stearylmethacrylate/methylaluminoxane) (PSMA/MAO) can stabilize metallocene systems leading to “nanoreactors” for ethylene polymerization in heterogeneous phase using low concentrations of activator.
