ABSTRACT:
The present invention provides a method for making a polymer dielectric composition incorporating diamondoids or diamond-like hydrocarbon units. The method includes forming a polymer solution from the cardo-diol 9,9-bis(4-hydroxyphenyl)fluorene and a diacid chloride, casting a freestanding thin polyester film from the polymer solution, and metallizing the polyester film with an evaporated Al layer to form the dielectric composition. The diacid chloride may be derived from trans-1,4-cyclohexanedicarboxylic acid; 1,3-adamantanedicarboxylic acid; or 4,9-diamantanedicarboxylic acid.
