Title:
OPTICAL MATERIAL COMPRISING CURABLE FLUOROPOLYMER
Document Type and Number:
WIPO Patent Application WO2002072706
Kind Code:
A8
Abstract:
A preferable optical material which has a stable structure containing ions of a rare earth metal and retains transparency in the visible light to the near infrared regions. The optical material is obtained by curing a fluororesin composition comprising (I) a fluoroprepolymer and (II) ions of a rare earth metal and/or a compound containing a rare earth metal element, the fluoroprepolymer (I) containing a curable fluoropolymer which (1) is an amorphous polymer having a fluorine content of 25% or higher and (2) has a curable part in a side chain of the polymer and/or at an end of the polymer backbone.
