AI Technical Summary
Existing cyclic olefin ring-opening polymer hydrides cannot simultaneously possess a suitable Abbe number and low birefringence, thus failing to meet the requirements for high Abbe number optical elements and low to medium Abbe number optical elements.
Hydrogenation of a cyclic olefin ring-opening polymer containing 1,2,3,3a,4,6a-hexahydro-1,2,4-methylbridged pentanene structural units and cyclic olefin monomer structural units with aromatic ring structures is carried out to form a cyclic olefin ring-opening polymer hydride with both moderate Abbe number and low birefringence.
This invention achieves cyclic olefin ring-opening polymer hydrides with moderate Abbe numbers and low birefringence, making them suitable for various molded materials, especially optical components, thus increasing the freedom of optical design.
