Block Copolymers Designer Soft Materials, For example thermoplastic elastomers are block copolymers containing a rubbery matrix polybutadiene or polyisoprene containing glassy hard domains often polystyrene. However rather than discuss further such a linear polar TPE macromolecule we will discuss some recently published data on the properties of PBA-b-PAN 3-arm star block copolymers78 These materials are polar TPEs with easily adjustable properties based on composition that retain their useful properties over a temperature range. A block copolymer is defined as a polymer comprising molecules in which there is a linear arrangement of blocks a block being defined as a portion of a polymer molecule in which the monomeric units have at least one constitutional or configurational.

Asymmetric Block Copolymers for Supramolecular Templating of Inorganic Nanospace Materials Bishnu Prasad Bastakoti World Premier International WPI Research Center for Materials Nanoarchitectonics MANA National Institute for Materials Science NIMS 11 Namiki Tsukuba Ibaraki 3050044 Japan. Block copolymers are a class of soft materials that self-assemble into well-defined mesophases on the nanometer length scale which creates opportunities in a variety of contemporary applications from advanced lithography to drug delivery. This class of macromolecules is produced by joining two or more chemically distinct polymer blocks each a linear series of identical monomers that may be thermodynamically incompatible like oil and vinegar.
