Abstract
A method for making a bicontinuous, conductive, pressure sensitive adhesive (PSA), such that the starting microemulsion has a convenient viscosity for coating, and such that only a single polmerization step is needed. This has been accomplished by the discovery of a class of thickening agents having a carboxylic acid functionality that are compatible with the microemulsion and yet do not damage the properties of the final adhesive.
