A novel perfluoroalkyl vinyl ether compound, a process for preparing a
copolymer by using the perfluoroalkyl vinyl ether compound, and an
optical plastic material comprising a copolymer prepared by the process
are provided. More specifically, the perfluoroalkyl vinyl ether has a
particular molecular structure; the process is performed by
copolymerizing the perfluoroalkyl vinyl ether compound with a common
fluorinated olefin in the presence of a perfluorinated radical initiator;
and the optical plastic material comprises a copolymer prepared by the
process and optionally a dopant.
