    • PURPOSE: To obtain a white fluorine-contained resin having low molecular weight useful as a lubricant, releasing agent, etc., having a controlled molecular weight, in high yield,by bringing a fluorine-contained polymer into contact with a fluorine-containing fluorine compound at a specific temperature.
      CONSTITUTION: 100pts.wt. fluorine-contained polymer such as powder,f pellet, scrap of sheet or polytetrafluoroethyllene, or filler-containing polytetraluoroethylene having small particle diameter is subjected to a contact reaction with ≤0.01pt.wt. calculated as F of a nitrogen-containing fluorine compound such as NF
      3 , N
      2 F
      4 , etc., which is stable at normal temperature, at 250W550°C, preferably at 350W500°C to give the aimed compound (wax) having improved lubricating activity, low surface energy, etc-.
      EFFECT: Since decomposition is carried out in the presence of active fluorine radical, the end of the reaction product is made into CF
      3 , the reaction product is extremely stable, carbon will not precipitate at all, the aimed white compound is obtained,and it is easily pulverized.
