PCT No. PCT/EP92/02557 Sec. 371 Date May 12, 1994 Sec. 102(e) Date May 12, 1994 PCT Filed Nov. 6, 1992 PCT Pub. No. WO93/10160 PCT Pub. Date May 27, 1993.The present invention relates to fluoropolymers with improved temperature resistance and dimensional stability in the heat based on fluoroethylenes, using perfluoro-(cycloalkyl-vinyl ethers) and optionally other monomers as comonomers. The invention also relates to the perfluor-(cycloalkyl-vinyl ethers) which impart the advantageous thermal properties to the fluoropolymers according to the invention.
