Abstract
Polimeri e copolimeri cristallini di olefine sotto forma di particelle sferiche aventi porosità (espressa come percento di vuoti) superiore a 15%, area superficiale (B.E.T.) superiore a 10 m2/g, in cui più dell'80% dei pori ha diametro maggiore di 1 micron. Tali materiali polimerici sotto forma di particelle trovano applicazione, ad esempio, nella preparazione di masterbatch contenenti quantità significative di additivi e/o pigmenti.
