Peter Hendrikus Vollenberg 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).

  • Light transmissive articles and methods thereof
    Patent number: 8765029
    Abstract: The present invention provides methods for controlling the optical properties of a light transmissive article. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. The method further includes selecting a first polymeric material from the reference polymeric materials and compounding the first polymeric material with a stable UV chromophore to provide a first polymer composition. The method further includes transforming the first polymer composition to provide the light transmissive article, wherein the light transmissive article has an Abbe number and a refractive index which falls within the target window. Light transmissive articles prepared using the above methods are also provided.
    Type: Grant
    Filed: December 5, 2006
    Date of Patent: July 1, 2014
    Assignee: Sabic Innovative Plastics IP B.V.
    Inventors: Eugene Pauling Boden, Brian Lee Lawrence, Steven James Montgomery, Shreyas Chakravarti, Peter Hendrikus Vollenberg, Edward Kung, Jan Henk Kamps, Lina Prada, John Brian McDermott, Michael Teruki Takemori

  • Non-linear styrenic polymer compositions and articles prepared therefrom
    Patent number: 6093781
    Abstract: Monovinyl aromatic polymer compositions with high melt strength, good flow and good heat properties which are suitable for fast injection molding, blow molding and thermoforming applications, comprising non-linear monovinyl aromatic polymers and copolymers having comb-type structures with 3 branches, star type structures with 4 to 6 branches, and/or dendritic structures in which the branches themselves have attached branched units. These compositions possess inherent melt strength and can be blow molded or thermoformed without sagging or molded into articles in shorter cycle times using less material than linear monovinyl aromatic polymers and copolymers with the same flow and heat distortion temperatures.
