  • Publication number: 20130338313
    Abstract: The invention is based on the discovery that a remarkable improvement in the performance of maleimide thermosets can be achieved by incorporating amide-extended maleimides into an adhesive formulation. Amide-extended maleimides described herein can be used to toughen bismaleimide thermosetting materials without sacrificing any thermal stability. Amide-extended maleimides are readily prepared by reacting a bismaleimide with an appropriate amine via the well-known Michael addition reaction. Acylation of the resulting secondary amines provides the amide-extended maleimide. The acylating agent can also be used to introduce polymerizable functional groups into the backbones of these thermoset monomers. Amide-extended acrylate and methacrylate monomers can also be prepared.

  • Patent number: 8211344
    Abstract: The present invention relates to the use of a microcrystalline polyamide for obtaining an object having all or part of its outer surface formed from this microcrystalline polyamide and having a particular surface finish, in which: the manufacture of the object comprises steps carried out hot between the Tg (glass transition temperature) and the Tm (melting point) of this microcrystalline polyamide; the transparency of the microcrystalline polyamide is such that the light transmission at 560 nm on a polished object 1 mm in thickness is greater than 80%, advantageously greater than 88%, the transparency being measured on the object obtained by standard processing methods, such as injection molding and sheet extrusion/calendering. Advantageously, the microcrystalline polyamide is such that its degree of crystallinity is greater than 10% and less than 30% (1st DSC heating according to ISO 11357 at 40° C.

  • Publication number: 20120149832
    Abstract: The invention relates to a non-aqueous dispersion of organic polymer particles in a reactive diluent. Said non-aqueous dispersion can be obtained in that at least one monomer is polymerized in the reactive diluent, forming the organic polymer particles, wherein the reactive diluent does not participate in said polymerization due to the orthogonal reactivity thereof relative to the monomers, but comprises a functionality allowing later targeted polymerization. Depending on the organic polymer particles or reactive diluents used, the non-aqueous dispersion can be used in multifaceted applications having a wide range of application profiles. In order to produce said non-aqueous dispersion, polymerization of at least one monomer in a stirred tank reactor in the presence of a reactive diluent is particularly suitable, wherein the conversion is performed at a stirring speed of at least 2 m/s, wherein the ratio of the stirrer diameter to the vessel diameter is set to 0.3-0.
