  • 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.

  • Patent number: 9988548
    Abstract: The invention relates to a molding composition modified for impact resistance, in particular to impact-resistant PMMA with improved optical properties at elevated temperatures, to molded items obtainable therefrom, and also to the use of the molding composition and of the molded items.

  • Patent number: 9987828
    Abstract: The present invention relates to novel matt PMMA foils for application on materials as foil providing protection from weathering effects and as decorative foil. In particular, the present invention relates to a novel, at least two-layer PMMA foil which features particularly good adhesion on the substrate. The outer layer here exhibits the mattness, and the inner layer here comprises a low-molecular-weight component which improves adhesion on the substrate.

  • Publication number: 20170361531
    Abstract: A three-dimensional object is formed by 3D printing, especially by a binder jetting method, in which particulate material in a powder bed is bonded by a printed adhesive. The particulate materials may be inorganic materials, for example sand or a metal powder, or particulate polymeric materials, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers. Powder bed compositions comprising core-(shell)-shell particles can be used for 3D printing, wherein the core-(shell)-shell particles can swell in contact with the binder during the printing operation.
