Abstract: The invention relates to a continuous method for producing dyed thermoplastic moulding materials in an extruder, as follows: I) in a first area, A) 10 to 99.999 wt. % of a thermoplastic polymer is metered into an extruder. II) In a subsequent area, B) 0.001 to 60 wt. % of a dye is added at a temperature below the particular glass transition temperature of the thermoplastic A). In the subsequent areas, the thermoplastic/dye mixture is heated, the polymer melt is homogenised and the resulting mixture is extruded.

Abstract: A process control method for melt extrusion of two materials, one with constant, the other with variable properties involves measuring one or more of the extrusion parameters and controlling the supply of one or both raw materials according to these measured parameters, the control being effected on the basis of a process model or property range relating the extrusion parameters to the supplied ratio of both materials. Process eqpt. includes eqpt. for measuring extrusion parameters and controlling the supply of at least one of the raw materials according to the claimed process.

Abstract: The invention relates to a fiber-reinforced thermoplastic moulding material containing the following ingredients in relation to the sum of ingredients A-D and optionally E and F, representing a total of 100 wt. %: d) 10-97 wt. % of at least one aromatic polyester as ingredient A; e) 1-50 wt. % of at least one particle-shaped grafted copolymer with a soft phase glass transition temperature that is lower than 0 DEG C and an average particle size of 50-1000 nm as ingredient B; f) 1-50 wt. % of at least one copolymer made of monomers c1) 50-90 wt. % of at least one vinyl aromatic monomer as ingredient C1 and c2) 10-25 wt. % acrylonitrile and/or methacrylonitrile as ingredient C2, as ingredient C; 1-50 wt. % glass fibers as ingredient D; f) 0-25 wt. % other ingredients that are compatible, can be mixed in a homogenous manner with ingredients A and/or C and can be dispersed therein, as ingredient E; f) 0-10 wt. % usual additives such as UV stabilizers, oxidation retarders, lubricating agents and release agents as ingredient F. The invention also relates to moulded parts made from said moulding materials and used in the interiors of motor vehicles. The invention further relates to the use of moulding materials in the production of moulded parts.
