✦ Synopsis

Microporous solids made by poi)merizing the organic phase of bicontinuous microemulsions stabilized with didodecyldimethylammonium bromide show surface areas as high as 70 m2/g. Small-angle X-ray scattering measurements on microporous copolymers containing polymethylmethaclylate show that these areas result from structures larger than 250 A that ar5generated during polymerization. These X-rays measurements also show that the 17-A structures characteristics of the original microemulsion are retained during polymerization, but destroyed when the detergent is extracted and the solid is dried. 0 * DDAB is didodecyldimethylammonium bromide.

These microemulsions consist of DDAB, water, and the hydrophobic monomer. 'These microemulsions consist of DDAB, decane, and the hydrophilic monomer.
