摘要： A BAND-PASS FILLER FOR TRANSMITTING A PRESELECTED BAND OF ULTRAVIOLET LIGHT IN THE WAVELENGTH RANGE OF ABOUT 1900 TO 4000 A. UNITS IS PREPARED BY INCORPORATING AN ULTRAVIOLET LIGHT ABSORBING COMPOUND IN A TRANSPARENT, MACHINABLE SOLID ORGANOPOLYSILOXANE PREPARED IN A PARTICULAR WAY. THE ULTRAVIOLET LIGHT ABSORBING COMPOUND PROVIDES (IN COMBINATION WITH THE RESIN) A SPECTRUM WITH AT LEAST TWO INTENSE ABSORPTION BANDS WITH A PRONOUNCED MINIMA BETWEEN THE ABSORPTION MAXIMA. THE ORGANOPOLYSILOXANE IS PREPARED BY HEATING A SILANE REPRESENTED BY THE FORMULA TSIZ3 IN WHICH T IS AN ALKYL GROUP SUCH AS METHYL OR AN ALKENYL GROUP SUCH AS VINYL OR AN ARYL GROUP SUCH AS PHENYL AND Z IS AN ALKOXY GROUP SUCH AS ETHOXY, WITH WATER, CONCENTRATING THE RESULTANT REACTION MIXTURE BY HEATING IT AT A TEMPERATURE OF ABOUT 100* TO 300*C. TO REMOVE BY-PRODUCT ALKANOL AND WATER, PRECURING THE CONCENTRATED PRODUCT BY HEATING AT A TEMPERATURE OF ABOUT 90* TO 185*C. TO PROVIDE A FURTHER CURABLE ORGANOPOLYSILOXANE. THE ULTRAVIOLET LIGHT ABSORBING COMPOUND GENERALLY IS MIXED WITH THE FURTHER CURABLE ORGANOPOLYSILOXANE WHICH IS THEN FORMED INTO AN ARTICLE ADAPTED FOR USE AS A FILTER IN SAID PRESELECTED WAVELENGTH.
