Disclosed is a polypropylene with an MFR of at least 20 g/10 min comprising a homopolypropylene and within a range from 2 wt % to 20 wt % of a propylene--olefin copolymer by weight of the polypropylene, where the homopolypropylene has a MFR within a range from 30 g/10 min to 200 g/10 min, where the propylene--olefin copolymer comprises within a range from 30 wt % to 50 wt % -olefin derived units by weight of the propylene--olefin copolymer, and has an IV within a range from 4 to 9 dL/g. The polypropylene may be obtained by combining a Ziegler-Natta catalyst having two transition metals with propylene in reactors in series to produce the homopolypropylene followed by a gas phase reactor to produce a propylene--olefin copolymer blended with the homopolypropylene.

The present application provides a block copolymer and uses thereof. The block copolymer of the present application exhibits an excellent self-assembling property or phase separation property, can be provided with a variety of required functions without constraint and, especially, etching selectivity can be secured, making the block copolymer effectively applicable to such uses as pattern formation.
