If the employment of polymerization auxiliaries in ammonium form is avoided in the preparation of a polytetrafluoroethylene having a content of 0.02 to 1% by weight of units of a perfluoro-(alkyl vinyl) ether by the suspension process, a polymer which does not tend to discoloration on heating is obtained.
