Producing a polyolefin composition with improved mechanical properties, useful for making semifinished or finished articles, comprises combining modified and unmodified polyolefins

摘要

Producing a polyolefin composition comprises adding an unmodified polyolefin (P1) to a composition (C2) comprising a polyolefin (P2) modified by grafting with optionally neutralized acid and/or anhydride functions, or adding P2 to a composition (C1) comprising P1, to give a composition with better mechanical properties than C1 and C2. An independent claim is also included for a semifinished or finished article comprising a polyolefin composition produced as above.
