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.
