Abstract: The invention relates to expandable polymer particles based on styrene polymers, to a process for the preparation thereof and to the use of the expandable polymer particles in a molded foam part. The polymer particles contain A) 87 to 99 wt. % of one or more styrene polymers (A), in relation to the total weight of (A), (B) and (C); B) 1 to 10 wt. % of one or more foaming agents (B); C) 0 to 3 wt. % of one or more nucleators or nucleating agents C); and optionally further additives (Z) in amounts which do not impair the domain formation and the foam structure resulting therefrom.

Abstract: A consumable filament and process for using the consumable filament in an extrusion-based additive manufacturing system made from or containing a heterophasic polypropylene composition having a xylene soluble content ranging from 15 wt % to 50 wt %, a melt flow rate MFR L ranging from 0.5 to 100 g/10 min, an intrinsic viscosity of the fraction soluble in xylene at 25° C. ranging from 1.5 to 6.0 dl/g, and an ethylene content ranging from 10 wt % to 50 wt %.

Abstract: The invention refers to a method for producing expanded polymer pellets, which comprises the following steps: melting a polymer comprising a polyamide; adding at least one blowing agent; expanding the melt through at least one die for producing an expanded polymer; and pelletizing the expanded polymer. The invention further concerns polymer pellets produced with the method as well as their use, e.g. for the production of cushioning elements for sports apparel, such as for producing soles or parts of soles of sports shoes. A further aspect of the invention concerns a method for the manufacture of molded components, comprising loading pellets of an expanded to polymer material into a mold, and connecting the pellets by providing heat energy, wherein the expanded polymer material of the pellets or beads comprises a chain extender. The molded components may be used in broad ranges of application.

Abstract: The invention relates to curable compositions which comprise epoxy resins, amino hardeners, and a phosphonate of the formula I. Addition of phosphonate of the formula I can give cured epoxy resins which have not only improved flame retardants but also an increased glass transition temperature when comparison is made with the corresponding resins without said addition.

Abstract: Bismaleimide resin systems and fiber reinforced prepregs prepared therefrom having exceptional toughness are prepared by dispersing into a bismaleimide base resin system preformed functionalized elastomer particles having a T.sub.g of less than 10.degree. C.

Abstract: A curable impact modified epoxy resin mixture suitable for producing high performance composites is composed ofA. an aromatic epoxy compound,B. an amine type curing agent,C. from 10 to 40% by weight of an aromatic thermoplastic oligomer which contains reactive groups, preferably a polyether sulfone, andD. from 0.1 to 10% by weight of a high molecular weight emulsifier, preferably a phenoxy resin, an epoxy resin or a thermoplastic copolymer, which is compatible not only with the epoxy compound A but also with oligomer C.

Abstract: Heat-curable bismaleimide resins contain a bismaleimide and a heterocyclic comonomer having terminal alkenyl or alkenyloxy groups. A preferred comonomer is 2,6-bis-(2-propenylphenoxy)-pyridine. The bismaleimide resins are suitable for the production of high performance composites.
