functional polymer
  1. Polymer that bears specified chemical groups.
  2. Polymer that has specified physical, chemical, biological, pharmacological, or other uses which depend on specific chemical groups.
    Examples of functions of functional polymers are catalytic activity, selective binding of particular species, @[email protected] and transport of @[email protected] carriers or energy, conversion of light to charge carriers and vice versa, and transport of drugs to a particular organ in which the @[email protected] is released.
