Beschreibung
Zusammenfassung:	Abrasian resistant protective coatings for plastic surfaces such as acrylics, polystyrenes and polycarbonates is provided by the plasma polymerization of at least one member of a group of organosilane compounds selected from a group consisting of vinyltrichlorosilane, tetraethoxyailane, vinyltriethoxysilane, tetravinylsilane, vinyltriacetoxysilane, hexamethyldisilazane, tetramethylasilane, vinyldimethylethoxysilane, vinyltrimethoxysilane and methyltrimethoxysilane. Plasms polymerization of these organosilane compounds provides an abrasion resistant protective coating for plastic optical surfaces together with a uniform optically clear layer in the 4,000 to 8,000 angstrom range. The advantages of applying plasma polymerization to the present organosilane compounds is further enchanced by the utilization of an additive gas during plasma polymerization to further increase the abrsion resistance of the protective coating.
