摘要： A process is disclosed for producing thermoplastics modified to be impact-resistant or polymer blends containing such modified thermoplastics. The thermoplastics or polymer blends contain: (A) 5 to 95 wt % of at least one water-wet elastomer component A which contains up to 60 wt % residual water; (B) 5 to 95 wt % of at least one thermoplastic polymer B; (C) 0 to 95 wt % of at least another polymer C; and (D) 0 to 70 wt % additives D. The elastomer component A is mixed with the thermoplastic polymer B, if available with the other polymer C and if available with the additives D in a screw-machine while mechanically dewatering the elastomer component A. The process is characterised in that components A, B, C and D are supplied to an extruder with at least two screws that rotate in the same or opposite directions and have a diameter Dscrew. Seen in the feeding direction (downstream), the extruder substantially consists of at least one dosing section in which the elastomer component A is supplied to the extruder by a dosing device; at least one squeezing section for dewatering the elastomer component A having at least one pressure element and at least a corresponding dewatering opening located upstream of the (first) pressure element at a distance therefrom equal to at least one screw diameter Dscrew; at least one feeding section in which the thermoplastic polymer B is fed into the extruder as a molten mass; at least one plasticising section fitted with mixing and/or kneading elements; at least one degassing section with at least one degassing hole in which the residual water is removed as steam; and an extraction zone. The water expelled through the dewatering openings is partially or totally present in the liquid phase, and components C and/or are supplied together or separately, either together with components A and/or B or separately from A and B in one or more of the above-mentioned extruder sections.

摘要： A method of preparing a dispersion of small particles in a polymeric precursor, which method involves providing a mixture of a particulate material and a surfactant in a nonaqueous solvent, forming a dispersion of the particulate material in the nonaqueous solvent, combining the resulting dispersion of particulate material in the nonaqueous solvent with a precursor material, and heating the combination of the dispersion of particulate material and the precursor material, with mixing, to a temperature sufficient to volatilize the nonaqueous solvent. The surfactant is soluble in the nonaqueous solvent and is adapted to stabilize the particulate material against agglomeration. The nonaqueous solvent swells the polymeric precursor near the boiling point of the nonaqueous solvent. The boiling point of the nonaqueous solvent is greater than a temperature at which the polymeric precursor may be mixed and below a temperature at which the polymeric precursor polymerizes or decomposes. In certain embodiments, the particulate material isan inorganic material. For example, the inorganic material may be a ferroelectric material, such as barium titanate and lead titanate. In other embodiments, the particulate material is a ferromagnetic material, such as magnetite and barium ferrite.

摘要： Inorganic material particles are dispersed in an aqueous medium with surface charge adjusting additives to give a moderately stable slurry or pigment grind. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to give the same performance as products including inorganic material dispersed with conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance properties with like levels of inorganic material.
