Zusammenfassung:	Disclosed herein are polycarbonate fibers and fibrous substrates, such as papers, containing such fibers. The polycarbonate fibers are produced from a polymeric composition comprising a cross-linkable polycarbonate containing endgroups derived from a monofunctional benzophenone or containing repeating units derived from a difunctional benzophenone. The polycarbonate fibers can be combined with other fibers to form the fibrous substrate. Upon exposure to ultraviolet light, crosslinking of the polycarbonate fibers will occur, improving various properties of the fibrous substrate. L'invention concerne des fibres de polycarbonate et des substrats fibreux, tels que des papiers, contenant de telles fibres. Les fibres de polycarbonate sont produites à partir d'une composition polymère comprenant un polycarbonate réticulable contenant des groupes terminaux dérivés de benzophénone monofonctionnel ou contenant des unités récurrentes dérivées de benzophénone difonctionnel. Les fibres de polycarbonate peuvent être combinées avec d'autres fibres pour former le substrat fibreux. Lors d'une exposition à une lumière ultraviolette, la réticulation des fibres de polycarbonate se produira, en améliorant diverses propriétés du substrat fibreux.
