Abstract
A dielectric film suitable for use in electrical condensers is made from a composition comprising a linear polyester derived from an aromatic dicarboxylic acid and a glycol and 0.01-0.5% of an inorganic pigment having a refractive index in the range 1.40-2.55 and a particle size between 0.01 and 10 microns. The polyester may be derived from a glycol of formula HOCnH2nOH, where n=2 to 10. Polymers specified are derived from terephthalic acid and ethylene glycol; terephthalic acid and 1,4 bis (hydroxymethyl) cyclohexane, isophthalic acid, terephthalic acid and 1,4-bis(hydroxymethyl) cyclohexane; bis (4-carboxyphenyl) sulphone, succinic acid and penta-1,4-diol and succinic acid, terephthalic acid and 1,4-bis (hydroxymethyl) cyclohexane. Pigments specified include SiO2, TiO2, ZrO2, Al2O3 and bentonite. The refractive index of the pigment may be within 30% of that of the polyester. The pigment may be added to the polyester-forming reactants before polymerization. In Example 1 N,N1 - di - b - naphthyl paraphenylene diamine is added as an antioxidant.
