Abstract
Disclosed are polyolefin/clay nanocomposites, comprising 40 to 99.9% by weight of polyolefins and 0.1 to 60% by weight of sepiolite-palygorskite type clays selected from the group essentially consisting of sepiolite and attapulgite. The nanocomposites in accordance with the present invention have excellent mechanical properties and thermal resistance. Also disclosed is a process for preparing the polyolefin/clay nanocomposites according to the present invention.
