Abstract: The use of thermoplastic polymers for the preparation of injection-molded articles and the resulting articles are described. Also described, is the use of a lubricated polyamide, obtained by means of the addition of at least one lubricant during the polyamide polymerization method, for the preparation of injection-molded articles.

Abstract: The subject of the present invention is yarns, fibers or filaments and also a textile article and a medical device obtained from said yarns, for improving skin cicatrization, in particular by activating collagen synthesis at the surface of the injured skin. The yarns, fibers or filaments of the invention comprise a polymeric matrix and inorganic fillers, uniformly dispersed in the polymeric matrix, having properties of absorption and/or of emission in the 2-20 ?m far-infrared region.

Abstract: Polymeric compositions containing additives having properties of emission and/or absorption of radiation in the long infrared region, and articles shaped therefrom are produced, including yarns and textile articles such as fabrics or knits; such additives include organic additives or inorganic fillers which have a capacity for absorption/emission of radiation in the infrared region, in a wavelength range of from 2 ?m to 20 ?m, and also a polymeric substrate, with the proviso that the inorganic fillers may be selected from among oxides, sulfates, carbonates, phosphates and silicates, and such inorganic fillers having an average particle size of less than 2 ?m.

Abstract: A method for producing a thermoplastic polymeric matrix includes adding a suspension containing a silicate compound and/or barium sulfate either before or during the polymerization of the polymerizable polymeric matrix; various articles are obtained by forming this polymeric matrix, such as yarns, fibers, filaments, films and molded articles.

Abstract: A cosmetic kit and the use thereof for improving the appearance of the skin is described. Further described, is the prevention and/or controlling of cellulite or the orange peel syndrome and/or for slimming down the figure, through the increase of the elasticity and firmness of the skin by stepping up collagen synthesis, for increasing blood microcirculation and for improving thermoregulation of the skin.

Abstract: The present invention refers to a process for manufacturing polyester comprising at least the following steps: (a) esterifying or transesterifying a carboxylic diacid or a dieester of a carboxylic diacid with a diol, (b) polymerizing in melt phase the esterification or transesterification product, (c) solidifying and granulating, (d) placing in contact the granules with a liquid swelling medium, and (e) post-condensing the granules in solid phase. The realization of the immersion step in a swelling medium permits increasing the kinetics of the solid phase post-condensation step.
