Abstract: 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.

Abstract: An antistatic composition, a transfer roller manufactured by using the antistatic composition, and a method of manufacturing the same are provided. The antistatic composition includes about 0.05 to about 5 parts by weight of an antistatic agent including a metal salt compound, about 10 to about 50 parts by weight of a thermoplastic elastomer, and about 100 parts by weight of a base resin. The antistatic agent includes the metal salt compound and an ether compound. The metal salt compound includes an alkali metal salt compound.

Abstract: A plasma display device and a method of driving a plasma display panel (PDP) are provided. The plasma display device includes an upper substrate on which a plurality of first electrodes and a plurality of second electrodes respectively corresponding to the first electrodes are formed; and a lower substrate on which a plurality of third electrodes are formed, wherein the first electrodes are respectively 100 ?m or more distant apart from the second electrodes, and during a reset period, a voltage that gradually increases is applied to the first electrodes, and at the same time, a positive bias voltage is applied to the third electrodes. Therefore, it is possible to reduce the power consumption of a PDP by driving a PDP including a scan electrode and an address electrode that are sufficiently distant apart from each other in such a manner that a positive bias voltage can be applied to an address electrode during a reset period.
