Surface chemical derivatization , defined

Almost all of the work diich has been done to date has involved a substrate of loosely defined stoichiometry, that is to say, an experimentally treated polymer surface of unknown composition. In several cases indicated, chemical reaction produced addition of an oiq gen species, which was not expected. For instance, no oxygen-containing reagent was used in the sodium-treated PTFE or in some of N2 or Ar corona-treated low-density polyethylene, yet copious amounts of oxygenated species were formed. What is needed for a method that can be said to quantitatively label the surface of a polymer is outlined below. Method Requirements for quantitative derivatization of polymers ...
