Abstract
The process of preparing low molecular weight polytetrafluorethylene by high temperature oxidation with potassium nitrate has been shown to lead to the formation of potassium fluoride in the polymer. This is found to absorb water vapour from the atmosphere forming its dihydrate KF.2H2O, a crystalline substance which shows a complex many line spectrum in the far infrared. The observed spectrum of KF.2H2O in the matrix differs in one major respect (the absence of a band at 73 cm−1) from that of pure KF.2H2O showing that there is some specific interaction between the dihydrate and its polymeric host.
