摘要

New thermoplastic fluorocopolymers and the fluoromonomers used for their preparation A b s t r a c t 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. 21
