    Abstract: Luminescent compositions are provided having improved color intensity and articles incorporating said luminescent compositions as security taggants, for example as anti-counterfeiting components in pharmaceutical packaging applications, or as aesthetic colorants that are generally usable in any application where luminescent coloration is desired. The luminescent compositions incorporate a particulate fluoropolymer that is blended with one or more luminescent pigments and/or luminescent dyes. These components are provided in a liquid medium in which the fluoropolymer particles are dispersed and with which the pigment(s)/dye(s) may or may not be soluble.

    Abstract: Methods for synthesizing stabilized polymers of chlorotrifluoroethylene and products manufactured using such polymers are disclosed herein. In one exemplary embodiment, a method for synthesizing chlorotrifluoroethylene (CTFE)-based polymers includes reacting, in the presence of an initiator and in a reaction medium at a pH of about 1.5 to about 2.5, one or more monomers comprising CTFE and after an amount of polymerization reaction time has passed, adding a neutralizing agent to the reaction medium to increase the pH of the reaction medium to within a range of about 1.8 to about 6.0.
