摘要：
High density polyethylene containing chromium catalyst residues is stabilized using a combination stabilizer system comprising 2,2'-ethylidene-bis(4,6-di-t-butylphenol), a solid polyol having from five to six carbon atoms and one alcoholic hydroxyl on each carbon, and a tris(alkylaryl)phosphite.
