POLYFLUOROALKADIENE MIXTURE AND METHOD FOR PRODUCING THE SAME

摘要

A polyfluoroalkadiene mixture represented by the general formula CF3(CF2)nCF=CH(CF2)m+1CH=CH2 [Ia] and the general formula CF3(CF2)n+1CH=CF(CF2)mCH=CH2 [Ib] (wherein n is an integer from 0 to 5 and m is an integer from 0 to 6) is obtained and manufactured as a mixed fraction of products [Ia] and [Ib] by causing an organic basic compound to react with a polyfluoroalkayl iodide represented by the general formula CF3(CF2)n+1CH2(CF2)m+1(CH2CH2)I [II]. This polyfluoroalkadiene mixture is a compound in which the number of CF2 groups linked to a perfluoroalkyl group is 5 or less, and is effectively used as a copolymeric monomer in the manufacture of resinoid- or elastomer-inclusive fluorine-based copolymers that are the active ingredient in finishing agents, such as a water repellants and mold release agents, etc.
