MULTI-STAGE PROPYLENE POLYMER, PROCESS FOR PRODUCING THE SAME, AND PROPYLENE RESIN COMPOSITION
摘要
<p>A multi-stage propylene polymer which comprises (A) 5 to 20 wt.%, based on the whole polymer, propylene homopolymer ingredient or propylene/C2-8 alpha-olefin copolymer ingredient each having an intrinsic viscosity [eta] higher than 10 dL/g as measured at 135°C in tetralin and (B) 80 to 95 wt.%, based on the whole polymer, propylene homopolymer ingredient or propylene/C2-8 alpha-olefin copolymer ingredient each having an intrinsic viscosity [eta] of 0.5 to 3.0 dL/g as measured at 135°C in tetralin.</p>
