Beschreibung
Zusammenfassung:	The present invention is directed to water-swellable, radiation curable compositions suitable for use in coating water-blocking fibers, such as optical fibers. The present invention is further directed to fibers, including optical fibers, which are coated with water-swellable exterior coatings that are configured to buckle and detach from the associated fiber to facilitate superior performance in longitudinal water-blocking testing. Also claimed and described are methods of applying such water-swellable coatings to optical fiber coatings. Further claimed and described are buffered bundles of fibers including at least one optical fiber that is coated with a water-swellable, radiation curable coating to ensure superior longitudinal water blocking performance.
