| 摘要 |
Amorphous copolymers of perfluoro-2,2-dimethyl-1,3-dioxole with tetrafluoroethylene and, optionally, with another ethylenically unsaturated monomer, have high glass transition temperatures, e.g., 85 DEG C or higher, low indices of retraction, and good physical properties which make them suitable for high-temperature, high-transparency applications. |
