| titleOfInvention | High stiffness propylene polymer compositions |
| abstract | A high stiffness propylene polymer compositions is described, comprising:n 100 parts by weight of crystalline propylene homopolymers, the relation between isotactic pentad ratio (P) and melt flow rate (MFR) being 1.00 ≥ P ≥ 0.015 log MFR + 0.955 and the isotactic pentad ratios (P) of extracts as obtained by successively extracting with boiling n-hexane and boiling n-heptane being, respectively, 0.450 to 0.700 and 0.750 to 0.930, or 100 parts by weight of crystalline ethylene-propylene block copolymers obtained by block copolymerizing 70 to 95% by weight, based on the total weight of the block copolymers, of propylene homopolymers obtained by polymerizing propylene at the first stage, having a relation between isotactic pentad ratio (P) and melt flow rate (MFR) of 1.00 a P Z 0.015 log MFR + 0.955, and 5 to 30% by weight, based on the total weight of the block copolymers, of ethylene, ethylene and propylene, ethylene, propylene and other a-olefins or propylene and other a-olefins from which ethylene has been removed at one or more stages, the ethylene content being 3 to 20% by weight based on the total weight of the block copolymers, and 0.01 to 1 part by weight of a phosphate compound represented by the general formula (I):n wherein all the symbols are as described in the specification. |
