Brominated vinylaromatic-diene block copolymers (Br-SBC) comprising a vinylaromatic polymer block S and a brominated diene polymer block BB, wherein before bromination the weight-average molar mass Mof the block S is greater than or equal to Mof the block BB, use thereof as flame retardants, and also polymer compositions comprising these for unfoamed and foamed thermoplastic polymers, for example EPS and XPS.

Brominated flame retardant

A composition comprising at least one expandable styrene polymer component and at least one cyclohexanecarboxylic ester and also optionally further components can be processed to mechanically robust foam materials.

Process for producing expandable styrene polymer compositions

The invention relates to a process and an apparatus for pelletizing polymer melts comprising blowing agent in a pelletizing chamber through which a liquid flows, its pressure being above the ambient pressure. In a first step, the polymer melt is injected into the pelletizing chamber, in a second step the polymer melt is cut via a cutting apparatus into individual pellets and, in a third step, the pellets produced in the pelletizing process are discharged with the liquid from the pelletizing chamber and are then isolated from the liquid. This process also comprises at least one of the following steps:

Method and device for granulating polymer melts containing blowing agent

The invention provides a process for preparing expandable styrene polymers which comprises the steps of:

Preparing expandable styrene polymers

Expandable pelletized styrene polymer materials with at least bi- or multimodal molecular weight distribution, to a process for their preparation, and to use for producing moldable-foam moldings.

Expandable polystyrene granulates with a bi- or multi-modal molecular-weight distribution

A process for the preparation of expandable styrene polymers having a molecular weight Mof greater than 170,000 g/mol, which comprises conveying a blowing agent-containing styrene polymer melt having a temperature of at least 120&#xb0; C. through a die plate with holes whose diameter at the die exit is at most 1.5 mm, and subsequently granulating the extrudate, and expandable styrene polymers (EPS) having a molecular weight Mof more than 170,000 g/mol with 0.05 to 1.5% by weight of internal water.

Method for producing expandable polystyrene

Continuous production process of expandable styrene polymer beads

Pigmented curable polyester molding compounds which cure to give homogeneously colored moldings contain an unsaturated polyester, copolymerizable monomers, a thermoplastic polymer and a color pigment and are prepared by dispersing the pigment in the molten thermoplastic in an extruder.

Preparation of pigmented curable polyester molding compounds

A thickened, uncrosslinked molding composition which has a long shelf life and can be cured above 50.degree. C. comprises a liquid reactive system, a thickener, a polymerization initiator and conventional additives. The thickener is a combination of a primary aromatic amine and an isocyanate. The molding compositions, which are, in particular, SMCs or BMCs, can be processed into moldings by compression molding, injection molding or transfer molding and subsequent curing.

Thickened molding compositions

Novel phenol compounds of the general formula ##STR1## where X is a sulfone group or contains a sulfone group, are suitable for the preparation of epoxy resins, vinyl ester resins, bismaleimide resins and cyanate resins.

Novel polyphenol and thermosetting plastics prepared therefrom

Molding materials having a long shelf life consist of an unsaturated polyester resin, monomers, conventional additives and an inhibitor combination comprising a phenol or quinone, a phosphine or an ester of phosphorous acid, and a metal cation in the form of a salt or a complex which is soluble in the polyester resin.

Molding materials based on curable unsaturated polyester resins and

Bismaleimides having the general formula ##STR1## in which n is a whole number between 5 and 70 and --X-- is --O-- or --NH-- are prepared through the reaction of the corresponding amino-terminated polyoxybutylenes with 2 moles of maleic anhydride. They are suited as toughening agents in high grade reactive resins.

Flexible bismaleimides
