  • Method of making a metallized plastic article
    Patent number: 5885497
    Abstract: It is possible to manufacture articles out of thermoplastic materials and to metallize the articles at their surface. In this way one can manufacture reflectors and similar articles. Most thermoplastic materials require processing steps prior to the metallization like application of primers, chemical etching and the like. The invention is based on the discovery that a certain type of materials can be metallized without any extra processing steps. The materials involved are polyestercarbonates or blends of polyestercarbonates and polycarbonate. This is quite surprising since polycarbonates can not be metallized in good quality without extra processing steps prior to the metallization step.
