Abstract
Official abstract text for this publication.
Use of porous metal oxide microspheres as light stabilizers for shaped artificial polymer articles, wherein the porous metal oxide microspheres are prepared via a process comprising forming a liquid dispersion of polymer nanoparticles and a metal oxide; forming liquid droplets of the dispersion; drying the droplets to provide polymer template microspheres comprising polymer nanospheres; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres.
