Abstract
The present invention provides a block polymer that comprises a plurality of block segments, wherein at least one block segment comprises a repeating unit having an ester moiety bonded to a main chain in a forward direction through a connecting group of two or more atoms, and the block polymer has a molecular weight distribution (Mw/Mn) of 1.3 or less. Also provided is a polymer composition containing the above block polymer and a functional material.
