RANDOM PROPYLENE COPOLYMER WITH HIGH COMONOMER CONTENT |
摘要 |
<p>The present invention relates to a propylene random copolymer, comprising comonomers selected from the group consisting of ethylene, C4 to C20 alpha-olefins, and any combination thereof, wherein the propylene random copolymer (a) has a comonomer content of at least 3.5 wt.-%, based on the weight of the propylene random copolymer, (b) has a randomness of at least 30 %, and (c) is prepared in the presence of a catalyst system comprising solid catalyst particles, wherein the solid catalyst particles (cl) have a specific surface area of less than 20 m2/g, (c2) comprise a transition metal compound which is selected from one of the groups 4 to 10 of the periodic table or a compound of actinide or lanthanide, (c3) comprise a metal compound which is selected from one of the groups 1 to 3 of the periodic table, and (c4) comprise inclusions not having catalytically active sites.</p> |
