Multi-Stage Propylene Polymer, Process For Producing The Same, And Propylene Resin Composition |
摘要 |
A multistage propylene-based polymer including the following components (A) and (B): (A) 5 to 20 wt % of a propylene homopolymer component or a copolymer component of propylene and an alpha-olefin with 2 to 8 carbon atoms having an intrinsic viscosity [eta] of more than 10 dL/g in tetralin at 135° C.; and (B) 80 to 95 wt % of a propylene homopolymer component or a copolymer component of propylene and an alpha-olefin with 2 to 8 carbon atoms having an intrinsic viscosity [eta] of 0.5 to 3.0 dL/g in tetralin at 135° C.
