Abstract (en)

[origin: US4174340A] In the case of polyolefins filled with alkaline earth metal carbonates, a very good compatibility of the hydrophilic filler and the hydrophobic polymer matrix is reached when using as adhesion promoters certain organo-phosphorus compounds. As a result, improved mechanical properties are obtained with the articles made of plastic material that has been prepared from such polyolefin molding compositions.

Abstract (de)

Bei mit Erdalkalicarbonaten gefüllten Polyolefinen wird eine sehr gute Verträglichkeit zwischen dem hydrophilen Füllstoff und der hydrophoben Polymermatrix erreicht, wenn als Haftvermittler bestimmte phosphororganische Verbindungen verwendet werden. Man erhält verbesserte mechanische Eigenschaften bei den aus derartigen Polyolefinformmassen hergestellten Kunststoffgegenstaänden.
