Robertus E. de Jong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metallized plastic article
    Patent number: 5503934
    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 extra 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.

  • Thermoplastic mixture comprising an agent to improve the lacquer bonding
    Patent number: 5500476
    Abstract: A polymer mixture on the basis of a polyalkylene phthalate ester, a copolyether ester and an agent to improve the impact to which an agent to improve the bonding of lacquer systems on an aqueous base has been added. The polymer mixture according to the invention comprises a polyalkylene glycol polymer or a polyalkylene glycol copolymer as an agent to improve the lacquer bonding.

  • Polymer mixture comprising aromatic polycarbonate, polybutylene terephthalate and polyalkylene glycol
    Patent number: 5348999
    Abstract: The invention relates to polymer mixtures which comprise an aromatic polycarbonate, a polybutylene terephthalate and a polyalkylene glycol. Due to the presence of the polyalkylene glycol a good lacquer bonding is obtained when lacquer systems on the basis of water are used.

  • Blends comprising a polyphenylene ether, a fluorine-containing olefinic polymer and a vinyl aromatic alkyl (meth) acrylate copolymer
    Patent number: 5155169
    Abstract: The invention relates to polymer mixtures which comprise a polyphenylene ether, a fluorine-containing olefinic polymer or copolymer and a vinyl-aromatic alkyl(meth)acrylate copolymer. Polymer mixtures having improved properties are obtained by the addition of a di- or triblock copolymer with one or more blocks derived from conjugated diene units and with one or more blocks derived from vinylaromatic units.
