Claim 1
Independent Claim
108 words
THE PROCESS OF PREPARING A PLASTICIZED POLYMER WHICH COMPRISES MIXING AN AQUEOUS DISPERSION OF COLLOIDAL SOLID POLYMERIZED TETRAFLUOROETHYLENE WITH FROM ABOUT 25% TO ABOUT 300% BY WEIGHT, BASED ON THE POLYMERIZED TETRAFLUOROETHYLENE, OF A SUBSTANTIALLY COMPLETELY FLUORINATED HYDROCARBON OIL DISTILLING AT TEMPERATURES IN THE RANGE OF FROM ABOUT 50*C. TO ABOUT 300*C. AT 10 MM. HG PRESSURE, COAGULATING THE DISPERSION WHILE STIRRING THE MIXTURE TO FORM A SUSPENSION OF THE COLLOIDAL POLYMERIZED TETRAFLUOROETHYLENE IN THE FLUORINATED HYDROCARBON OIL, SEPARATING THE SUSPENSION FROM THE AQUEOUS PHASE, AND HEATING THE SUSPENSION AT A TEMPERATURE OF FROM ABOUT 327*C. TO ABOUT 375*C. UNTIL THE MIXTURE CONVERTS TO A HOMOGENOUS PLASTIC MASS.
