Document Type and Number:
Japanese Patent JPH04500374
Kind Code:
A
Abstract:
A compound having at least one perfluorovinyl group and at least one functional group is suitable for reacting with and/or forming polymers. The compound is preferably of Formula I: (G)n-R-(X-CF=CF2)m wherein R represents an optionally substituted hydrocarbyl group, X represents any group which links R and a perfluorovinyl group; n is the number of G groups, m is the number of (XCF=CF2) groups; and G represents any reactive functional group of a group convertible into a reactive functional groups. A process for preparing a compound of Formula I comprises the steps of: (a) preparing a 2-halotetrafluoro compound of the formula III: (Q-CF2-CF2X)m-R-(G'')n wherein R, X, m and n are as described for Formula I and Q is bromine, chlorine or iodine; and G'' is a functional group, or a functional group suitable for conversion into G; (b) chemically modifying group G'' to produce functional group G; and (c) dehalogenating the 2-halotetrafluoro compound to form the corresponding trifluorovinyl compound.
