Patents by Inventor Andrea Fruth

Andrea Fruth 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).

  • Patent number: 10695978
    Abstract: The present invention relates to the technical field of 3D printing, especially in the form of the binder jetting method, in which particles in a powder bed are bonded by means of a printed adhesive to form a three-dimensional object. The particles may be inorganic particles, for example sand or a metal powder, or polymeric particulate, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers.
    Type: Grant

  • Publication number: 20200071513
    Abstract: A process is for preparing polymeric particles for use as impact modifiers in curable (meth)acrylic resin compositions. Further, the process relates to a cured (meth)acrylic resin composition, in particular to adhesive or coating materials containing polymeric particles dispersed in a cured (meth)acrylic resin matrix. Said composition can be advantageously used as an adhesive, coating or a composite material.

  • Publication number: 20200017622
    Abstract: A polymeric particle has an average diameter from 300 nm to 1000 nm and includes an outer layer, containing a cross-linked polymer A, and a first inner layer, containing a cross-linked polymer B, distinct from the cross-linked polymer A. The cross-linked polymer A is obtainable by emulsion polymerisation of a reaction mixture including at least one (meth)acrylic monomer, a cross-linking monomer A, a polymerisation initiator and a chain transfer agent.
