Abstract
A polyfluoroallyl ether of the formula: ##STR1## wherein each X, which is the same or different, is a chlorine atom or a fluorine atom and each Y, which is the same or different, is a hydrogen atom, a chlorine atom or a fluorine atom, which is useful as a modifier for polymers.
Claims21
A polyfluoroallyl ether of the formula:
- ##STR6## wherein each X, which is the same or different, is a chlorine atom or a fluorine atom and wherein each Y, which is the same or different, is a hydrogen atom, a chlorine atom or a fluorine atom.
A process for preparing polyfluoroallyl ethers of the formula:
- ##STR7## wherein each X, which is the same or different, is a chlorine atom or a fluorine atom and wherein each Y, which is the same or different, is a hydrogen atom, a chlorine atom or a fluorine atom, which comprises reacting a fluoroketone cyanohydrin salt of the formula:
- ##STR8## wherein M is an alkali metal and each Y is as defined above with a fluoropropenyl halide of the formula:
- CFX.dbd.CX--CF.sub.2 --Z
- wherein Z is a halogen atom except fluorine and each X is as defined above.
