ABSTRACT:
Perfluoro(2,2-dimethyl-1,3-dioxole) forms oligomers on standing in the presence of an ether. The preferred ethers are aliphatic and cycloaliphatic, especially tetrahydrofuran. Free radical generators, especially peroxydicarbonates, may be added to the reaction medium. The oligomers have a degree of polymerization of about 2-8. They are useful as lubricants, hydraulic fluids, heat transfer agents, and plasticizers, and as intermediates to oligomeric acid fluorides and acids, which acids are useful surfactants.
