<p>Hexafluoropropylene oxide (HFPO) compounds, including polymers, expressed by the general chemical formula (1) below: <CHEM> wherein R<1> is a single bond, an alkylene group of 1 to 10 carbon atoms, or said alkylene group in which a part of, or all of, the hydrogen atoms are substituted by fluorine atoms, Rf is a fluorine atom, a perfluoroalkyl group of 1 to 10 carbon atoms, or a perfluoroalkyl ether group, and n is 0 or an integer of at least 1. A manufacturing method for the HFPO compounds which is characterized by the reaction between hexafluoropropylene oxide and a vinyl group containing compound, expressed by the general chemical formula (2) below: <CHEM> wherein R<1> and Rf are same as above. The compounds have utility as important intermediate raw materials for the production of novel functional silicone compounds having HFPO polymer units.</p> |
