FIELD: polymer production.
SUBSTANCE: process comprises polymerization of tetrafluoroethylene in presence of aqueous medium and polymerization initiator. Impurity level in tetrafluoroethylene to be polymerized does not exceed 100 ppm. Impurities contain saturated compound depicted by general formula CnHmFjClk (n is integer equal to 1 or 2 and m, j, and k are independently integers from 0 to 4, while j+k+m = 2n+2) and at least one saturated compound selected from group consisting of CF2=CFH, CF2=CFCl, CF2=CH2, CFH=CH2, CFH=CHCl, CFH+CCl2, CFCl=CH2, CFCl=CHCl, and CFCl=CCl2.
EFFECT: enabled production of homogenous and high-stretchable tetrafluoroethylene showing excellent properties regarding fibrillation and having high rupture strength.
