Heterophasic propylene polymerization material
A heterophasic propylene polymerization material containing a propylene homopolymer component or a specific propylene copolymer component, and a specific ethylene-α-olefin copolymer component, in which (i) the amount of the xylene-soluble component is 40% by weight or more, (ii) the limiting viscosity [η]C X I S of the xylene-insoluble component is 1.50 dL/g or more, (iii) the ratio of the limiting viscosity [η]C X S of the xylene-soluble component to the limiting viscosity [η]C X I S of the xylene-insoluble component is 1.5 or less, and (iv) the content of monomer units derived from ethylene and α-olefins having 4 to 12 carbon atoms in the xylene-insoluble component is 6% by weight or more.
