Use the perfluoropolyether surface active agent includes the water emulsification polymerization of the fluorine conversion

摘要

This invention regards the water emulsification polymerization of the fluorine conversion monomers which use next formula (i) or the Pell fluoro poly- ethers (ii). Especially, the Pell fluoro poly- ether surface active agent corresponds to formula (i) or (ii) CF₃ - (OCF₂) _{m O CF2 X} (i) (In formula, m is value 1 - 6, X shows carbon acid radical or those salts); CF₃ O (CF₂) ₃ - (OCF (CF₃) cf2) _{z O L Y} (ii) (In formula, z 0, 1, to be 2 or 3 value, as for L cf (CF₃) -, the connected basis of two value which is selected from cf2 and cf2cf2 is shown, Y shows carbon acid radical or those salts). This invention furthermore regards the water dispersed liquid of the fluoro polymer which possesses the above-mentioned Pell fluoro poly- ether surface active agent.
