    Abstract: Process for the impregnation of a polymer substrate including at least one polymer, which comprises putting said polymer substrate in contact with at least one aqueous emulsion, preferably an aqueous microemulsion, including at least one organic additive. The impregnated polymer substrate obtained from said process can be advantageously used for obtaining polymer end-products having improved aesthetic characteristics (for example, impregnation with at least one dye) or stability characteristics (for example, impregnation with at least one stabilizer), which can be used in various fields such as, for example, the optical field (e.g., advanced optical components, laser applications), the medical field (e.g., the release of pharmaceutical substances), the agricultural field (e.g., release of pesticides), fragrances (e.g., release of fragrances). More specifically, said polymer substrate can be used in luminescent solar concentrators (LSCs) which, in their turn, can be advantageously used together, for example, with photovoltaic cells (or solar cells), or photoelectrolytic cells, in solar devices (i.e. devices for exploiting solar energy). Furthermore, said luminescent solar concentrators (LSCs) can be advantageously used together, for example, with photovoltaic cells (or solar cells), in photovoltaic windows.

    Abstract: The present invention relates to a polymer composition having improved scratch resistance properties, the composition comprising (i) one or more polymers with a glass transition temperature (Tg) of at least 25° C., and (ii) solid particulate material having a surface modified with an organic modifier of formula (I), an organic modifier of formula (I) being the only organic modifier used to modify a surface of the solid particulate material, wherein the solid particulate material is distributed at least throughout a surface layer of the one or more polymers, and wherein the improved scratch resistance is relative to that of the one or more polymers absent the distributed particulate material, (I) where R is selected from a quaternary ammonium cation, a quaternary phosphonium cation, and imidazolium cation and a pyridinium cation; x is an integer ranging from 1-5; Ry is selected from OH, C(O)OH, NH2, SH and CH3; and Z is a counter anion.
