HETEROPHASIC POLYMER COMPOSITION OF HIGH STIFFNESS
摘要
<p>The present invention relates to a heterophasic polymer composition which comprises (i) a matrix comprising a propylene homopolymer and/or a propylene copolymer having an amount of comonomer units of less than 1.0 wt%, and (ii) an elastomeric polypropylene which is dispersed within the matrix and comprises comonomer units derived from ethylene and/or a C4 to C12 alpha-olefin; and wherein the heterophasic polymer composition has an amorphous fraction AM in an amount of 2.0 to 7.5 wt%, and the amorphous fraction AM has an amount of ethylene- and/or C4 to C12 alpha-olefin-derived comonomer units of 20 to 45 wt%.</p>
