    Abstract: The invention relates to a method of producing styrene monomers by depolymerization (breakdown) of a styrene-copolymer-containing polymer mass, a device for carrying out the method, the use of a styrene copolymer for producing styrene monomers by thermal depolymerization and the use of a styrene copolymer as an additive in the thermal depolymerization of polystyrene. The polymer mass contains I) 10 to 100 wt %, relative to the total weight of the polymer mass (A), of a styrene copolymer (I), comprising: Ia) 10 to 99 wt %, relative to the styrene copolymer (I), of repeating units (Ia) that originate from styrene; and Ib) 1 to 90 wt %, relative to the styrene copolymer (I), of repeating units (Ib) that originate from a monomer the homopolymers of which have a ceiling temperature of below 350° C.; and II) optionally 0 to 90 wt % polystyrene (II).

    Abstract: The invention relates to a method for producing styrene monomers by the depolymerisation of polystyrene in the presence of foreign polymers, such as polyolefins. Said method comprises the following steps: a) introducing a polymer composition (A) containing: I) 10 to 99.5% by weight, based on the polymer composition (A), of polystyrene (I); and II) 0.1 to 89.9% by weight of polyolefin (II); and/or III) 0.1 to 4.9% by weight of acrylonitrile-based polymer (III); and/or IV) 0.1 to 4.9% by weight of polyester (IV), into the reaction zone (R) of a pyrolysis reactor (P); b) thermal cracking the polystyrene contained in the polymer composition (A) in the reaction zone (R) of the pyrolysis reactor (P) at a temperature of between 400-1000° C., c) removing the product mixture (G) obtained from the reaction zone (R), d) cooling of the product mixture (G), and e) separating the styrene monomers from the further components.

    Abstract: The invention relates to a fibre-reinforced composite (K) comprising: (A) ≥50 wt.-%, based on the total weight of the fibre-reinforced composite (K), of at least one continuous fibrous reinforcement material; and (B) 0 and ≤3 wt.-%, derived from monomer moieties which are appropriate to interact with the surface of the fibrous reinforcement material (A), in particular of repeating units derived from maleic acid anhydride or maleic acid, and wherein less than 10% of the number of the reinforcement fibres present at a fracture surface of the fibre-reinforced composite (K) protrude from the fracture surface with a length of more than 5 times the diameter of the fibre.
