Polymers composed of macromolecules containing exclusively alternating arenediyl or heterarenediyl (formerly arylene or heteroarylene, respectively) and ethynediyl (formerly ethynylene) constitutional repeating units in the backbone:
where Ar is a divalent arenediyl or heterarenediyl group (structure-based polymer class name).
Note:
A polymer for which Ar is phenylene is a polyphenyleneethynylene.
A polymer for which Ar is phenylene is a polyphenyleneethynylene.
