Process for the preparation of stabilized olefin polymers |
摘要 |
A process is described for the preparation of olefin polymers by polymerization over a transition metallocene catalyst with the addition of at least one phosphorus(III) compound, sterically hindered amine, sterically hindered phenol or acid scavenger, alone or in combination with one another; the polymers which can be obtained in this way are of outstanding stability.
