Fluorinated tris-epoxides based on triphenyl methane

摘要

Epoxides of the invention are those of the formula ##STR1## wherein J is H or F, the same in each occurrence; Q is a valence bond or - -O--, the same in each occurrence; and Y is H or F, independently. When cured, these epoxides are superior in moisture resistance, flame retardance, and thermal stability to the corresponding non-fluorinated, prior art epoxides. The epoxides of the preceding formula may be made by first reacting an allylic halide of the formula CJ.sub.2 ═CJ--CJ.sub. 2 --X, wherein X is halogen, with a compound of the formula ##STR2## wherein Z is MO, hal.Mg or Ag; M is an alkali metal; and hal=Br or I; then if Y is to be F, converting the --CH group to a --CF group, and finally, oxidizing the CJ.sub.2 ═CJ group to a ##STR3## group.
