Antimicrobial compositions containing a carboxylic acid, for example, a fatty acid, and a carrier medium including a freezing point depressant are disclosed. Such dielectric structures show increased adhesion of subsequently applied conductive layers. The downstream can be DSL or HFC. The outcoupling mirror and the phase-conjugate mirror form a main cavity. In another aspect, the present invention provides a polymer electrolyte membrane comprising the fluoropolymer made according to the method of the present invention which is free of added emulsifier. Embodiments of the invention can smoothly transition from a rope clamping position to a rope unclamping position, conveniently providing an effective rope control device.
