Title (EN) CYCLIC DIHYDROGENPOLYSILOXANES, HYDROGENPOLYSILOXANES, PROCESSES FOR THEIR PRODUCTION, SILICA TYPE GLASS MOLDINGS AND A PROCESS FOR THEIR PRODUCTION, OPTICAL ELEMENTS AND A PROCESS FOR THEIR PRODUCTION
(FR) DIHYDROGENPOLYSILOXANES CYCLIQUES, HYDROGENPOLYSILOXANES, PROCESSUS DE PRODUCTION DE CELLES-CI, MOULAGES DE VERRE DE TYPE SILICE ET PROCESSUS DE PRODUCTION DE CEUX-CI, ELEMENTS OPTIQUES ET PROCESSUS DE PRODUCTION DE CEUX-CI
Abstract: front page image
(EN)Cyclic dihydrogenpolysiloxanes, hydrogenpolysiloxanes of specific siloxane unit formulas etc., a process for their production using hydrolysis/condensation, a process for the production of silica type glass moldings with an optical transmittance of 90% to 100% in the vacuum-UV region to UV region and an optical transmittance of 98% to 100% in the visible region to near infrared region by curing said cyclic dihydrogensiloxanes or said hydrogenpolysiloxanes in a mold, said silica type glass moldings, optical elements made up of the silica type glass, a process for the production of optical elements having such a silica type glass film layer by coating an optical element with the hydrogenpolysiloxanes and curing them, and optical elements having such a silica type glass film layer.
(FR)La présente invention concerne des dihydrogenpolysiloxanes cycliques, des hydrogenpolysiloxanes de préparations d'unité de siloxane spécifiques etc., le processus de production de celle-ci au moyen d'une hydrolyse/condensation, un processus de production de moulages de verre de type silice avec une transmission optique de 90 % à 100 % dans la région UV sous vide à la région UV et une transmission optique de 98 % à 100 % dans la région visible à la région proche de l'infrarouge par traitement de ces dihydrogensiloxanes cycliques ou de ces hydrogenpolysiloxanes dans un moule, ces moulages de verre de type silice, ces éléments optiques fabriqués à partir de ce verre de type silice, un processus de production d'éléments optiques possédant un film de verre de type silice par recouvrement d'un élément optique avec les hydrogenpolysiloxanes et par traitement de ceux-ci et, des éléments optiques possédant ce film de verre de type silice.
