FILLED TPO COMPOSITIONS, METHODS OF MAKING THE SAME, AND ARTICLES PREPARED FROM THE SAME |
摘要 |
<p>Compositions comprising (i) a crystalline, isotactic propylene homopolymer, (ii) an ethylene/a-olefin elastomeric impact modifier, and (iii) a reinforcing grade of filler, for example, talc. The crystalline isotactic propylene homopolymer has a flex modulus of greater than about 1930 MPa and a heat deflection temperature (HDT) of greater than about 100 °C; the ethylene/a-olefin interpolymer has a Tg of less than about -30 °C, and a tan delta measured at 0.1 radians/s at 190 °C of less than about 2; and the filler has a HDT reinforcing efficiency of at least about 2. The composition has an HDT of greater than about 100 °C and a flex modulus of greater than about 1930 MPa.</p> |
