Hexafluoroisopropylidene-containing Polyheteroarylenes

The methods of synthesis of various condensation monomers containing the hexafluoroisopropylidene groups and the polyheteroarylenes based on them are examined. The influence of the hexafluoroisopropylidene groups incorporated in the main chains of the macromolecules is analysed and it is shown that polyheteroarylenes containing these are characterised by an improved solubility and fire resistance and that the articles based on them have a higher elasticity.
