Summary

Polyethylene obtained both on supported catalysts and on Ti-Al systems with donor ligands has molecular mass higher than polyethylene prepared on conventional systems. It was necessary to modify the viscometric determination of molecular mass of such samples of polyethylene to determine it in the range higher than 700 000.
