Definitions
- ttm fil i where the phenylene radical is either para-phenylene, meta-phenylene or mixtures thereof, and the polymer contains a sufiicient number of the units to provide a polymer having an inherent viscosity of at least 0.3, measured on a 0.5 percent by weight solution in concentrated sulfuric acid or other solvent at 30 C.
- the above polyketones and copolyketones are useful as high temperature electrical insulation.
