PCT No. PCT/US97/23861 Sec. 371 Date Aug. 5, 1998 Sec. 102(e) Date Aug. 5, 1998 PCT Filed Dec. 22, 1997 PCT Pub. No. WO98/29491 PCT Pub. Date Jul. 9, 1998A polymer composite comprising a hydroxy-phenoxyether or polyester polymer matrix having dispersed therein layers of an inorganic material derived from a multilayered inorganic material having organophilic properties. The dispersion of the multilayered inorganic material in the polymer matrix is such that an increase in the average interlayer spacing of the layered inorganic material occurs. This increase in interlayer spacing occurs to a significant extent resulting in the formation of a nanocomposite. The polymers are preferably derived from a diglycidyl ether or ester or an epihalohydrin and a dinucleophile such as a dicarboxylic acid, a difunctional amine, a bisphenol or a sulfonamide. As the organophilic inorganic material clay minerals modified with organic ammonium compounds are used. |
