Title:
DEUTERATED CYCLIC OLEFIN POLYMER
Document Type and Number:
Japanese Patent JP2005226015
Kind Code:
A
Abstract:
To provide a polymer material improved in transparency in a visible light region and an infrared region in electric/electronic material and optical material, particularly optical waveguide material field.
The subject deuterated cyclic olefin polymer has a recurring unit represented by formula [2] (wherein (n) is an integer of ≥0; R1 to R12 are each hydrogen atom, deuterium atom or a 1-15C hydrocarbon group and at least one of R1 to R12 is deuterium atom; A1 to A4 are each hydrogen atom, a 1-15C hydrocarbon group or a deuterated cyclic hydrocarbon group or a substituent group containing a hetero atom such as boron, nitrogen, oxygen, phosphorus or sulfur and A1 to A4 may each together form a ring structure).
