The invention relates to an improved process for providing purified styrenic monomers, such as styrene, from styrene-containing polymer waste. Styrene-containing waste is depolymerized in a suitable reactor, and the depolymerization products are condensed and separated in a three-step distillation process.

Process for de-polymerization of styrenic monomer-containing polymers and for retrieval of styrenic monomers

The invention relates to thermoplastic compositions, containing the following components: a) 30 to 90 wt % of one or more styrene copolymers, and acrylonitrile, as component A; b) 10 to 70 wt % of several impact-modifying graft rubbers without an olefinic double bond in the rubber phase as component B, wherein said component B contains: B1) 1 to 50 wt % of rubber particles that have an average particle diameter of 50 to 150 nm as component B I; B2) 50 to 99 wt % of rubber particles that have an average particle diameter of 800 to 1200 nm as component B2; c) 0 to 20 wt % of one or more additives as component C; are especially weather-resistant and have good mechanical properties.

Matt weather-resistant molding masses for extrusion methods

The invention relates to a method for producing hollow bodies having freely displaceable particles enclosed in the hollow body, wherein a) a gel-forming liquid in which the particles are suspended is brought into a cross-linking bath, b) the gel cores that form are isolated, c) the cores are coated with a composition comprising sinterable material and a binder, and d) the coated cores are subjected to a heat treatment wherein the gel and the binder are expunged and the sinterable material is sintered into a closed shell. The gel forming material is, for example, sodium alginate, and the cross-linking bath comprises calcium ions. The particles are selected, for example, from ZrO, AlO, TiO, and SiOor mixtures thereof. The sinterable material is, for example, a metal powder such as carbonyl iron powder.

The present invention relates to a novel process for the anionic polymerization of lactam monomers.

Process for polymerizing lactam

The invention relates to a process for preparing polymers from monomers and/or oligomers by adding a liquid comprising the monomers and/or oligomers dropwise to a continuous liquid phase in a reactor, the continuous liquid phase being immiscible with the liquid comprising the monomers and/or oligomers, and the monomers and/or oligomers reacting in the continuous liquid phase to give the polymer. The liquid comprising the monomers and/or oligomers is shaped to droplets outside the continuous liquid phase, which are subsequently introduced into the continuous liquid phase. The invention further relates to a reactor for performing the process, comprising a tube through which a continuous liquid phase flows, and means of generating droplets, the means of generating droplets being arranged such that the droplets are generated outside the continuous liquid phase and then introduced into the continuous liquid phase.
