POLYOLEFINS CONTAINING CATALYST RESIDUES STABILIZED WITH TRIALKANOLAMINETRISPHOSPHITES

摘要

Polyolefins prepared using new supported catalysts the residues of which are not removed from said polyolefin exhibit difficult stabilization problems, especially poor weatherability, caused by the presence of said residues still remaining in the polyolefin. The use of trialkanolamine trisphosphites ameliorates these stabilization difficulties and leads to excellent polymer stabilization inspite of the catalyst residues.
