ABSTRACT:
Fluorinated aliphatic long chain addition polymers comprised of at least one monomer having at least one fluorine atom attached to a chain carbon atom are used in various environments for their ability to reflect a high percentage of incident light having a wave length in the 2400 to 8000 Angstrom region. These reflectance polymers may be in pressed powder form or in film form and thus are especially applicable as reflectance standards and reflectance coatings particularly in light integrating spheres of spectrophotometers.
