    摘要： The invention relates to a composition (C) for the injection moulding of articles, comprising or consisting of a first compound (A), including a polymer matrix, at least one weak organic acid, at least one inert aesthetic additive; and a second compound (B), including a polymer matrix, at least one carbonate or bicarbonate salt of, at least one inert aesthetic additive, wherein the first compound (A) is in a concentration comprised between 34% and 40% by weight, and the second compound (B) is in a concentration comprised between 60% and 66% by weight. The invention also relates to a process for the injection moulding of an article comprising or consisting of composition (C), comprising the steps of: preparing the composition (C), loading the composition (C) into an injection moulding plant, moulding an article under certain conditions. The invention also relates to an extrusion process for producing granules comprising or consisting of the first compound (A), or granules comprising or consisting of the second compound (B), comprising the steps of: preparing a polymer matrix comprising or consisting of one or more virgin-type thermoplastic polymers, and/or one or more recycled plastic materials; combining and mixing with the polymer matrix at least one inert aesthetic additive, and at least one weak organic acid, or at least one carbonate or bicarbonate salt, so as to obtain a precursor (a) of the first compound (A) or a precursor (b) of the second compound (B); loading the precursor (a) of the first compound (A) or the precursor (b) of the second compound (B) into an extruder; extruding under certain conditions; cutting the extrudate under certain conditions. Finally, the invention also protects artefacts comprising or consisting of the composition (C), which can be obtained by the above-mentioned injection moulding process.
