Abstract
Tetrafluoroethylene is polymerised by the suspension process in the presence of modifiers. The modifiers employed are from 0.0004 to 0.0029 mol %, based on the tetrafluoroethylene, of a compound of formula I and/or II or of the formula III. Rf and n are as defined in Claim 1 or 2. The polymers prepared according to the invention can be used to produce press-sintered blocks without cracking. <IMAGE>
