Abstract:
A flexible propylene resin, which comprises:(x) 10 to 90 weight % of boiling heptane soluble polypropylene having an intrinsic viscosity of not less than 1.2 dl/g, and(y) 90 to 10 weight % of boiling heptane insoluble crystalline isotactic polypropylene having an intrinsic viscosity of 0.5 to 9.0 dl/g,said resin having a pentad fraction (rrrr/(1-mmmm)), measured by .sup.13 C-NMR, expressed as a percentage, of not less than 20%, and a domain structure which is observed by a transmission type electron microscope, all intrinsic viscosities being measured in a decaline solution at 135.degree.
