Process for producing metallized multi-layer bodies from special polycarbonates

摘要

Preparing multilayered bodies comprises converting a substrate material containing a copolycarbonate having at least one bisphenol unit (II) and/or a phenol structural unit (I) (as end group) to a molded body; and pretreating the molded body with an air or argon based plasma and subsequently metalizing the obtained product in a direct current-magnetron sputter process, where the copolycarbonate has a Vicat softening temperature of greater than 160[deg] C according to DIN ISO 306.
