| description | PURPOSE:To form a chemical-resistant, wear-resistant surface layer, by activating the surface of a molded plastic optical part with plasma, grafting a vinylsilane compd. onto said surface and oxidizing the surface with oxygen plasma. CONSTITUTION:A plastic optical part 5 is placed within a vacuum treating chamber 1 provided with reticular electrodes 2, 3. An inert gas such as argon is introduced through an inlet 7 thereinto to generate plasma, whereby stains on the surface layer of the optical part 5 are removed and said surface is activated. A vinylsilane compd. 8 such as dichloromethylvinylsilane is introduced and grafted onto the surface layer of the activated high-molecular compd. Oxygen is then introduced through an inlet 7 to generate oxygen plasma which then oxidize side chains composed of the vinylsilane compd. grafted onto the high- molecular compd., thus forming a chemical-resistant, wear-resistant surface layer. |
