block copolymer
A @C01335@ that is a @B00685@. In the @C01281@ macromolecules of a @B00682@ @C01335@, adjacent blocks are constitutionally different, i.e. adjacent blocks comprise @C01288@ derived from different species of @M04017@ or from the same species of @M04017@ but with a different composition or @ST06775@ distribution of constitutional units.
