  The present invention relates to an aqueous suspension of nanocapsules containing, in an aqueous medium, nanocapsules comprising a polymer shell and a lipid core containing an oily solvent, characterized in that the said lipid core contains at least one steroid chosen from: DHEA, its chemical and biological precursors and its chemical and metabolic derivatives, and in that the said oily solvent comprises at least one compound chosen from certain classes of solvents for DHEA. The invention also relates to a cosmetic and/or dermatological composition comprising the said suspension of nanocapsules in a physiologically acceptable medium. Finally, the invention relates to the cosmetic and dermatological uses of this composition, especially for preventing or treating the signs of ageing of the skin.

  Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranched polymers, star shaped polymers or star branched polymers) or has not been disclosed in the prior art. The high number of end-groups per molecule of dendritic polymer combined with their unique globular architectures leads to large intergallery spacings when intercalated in layered silicates and particularly facile exfoliation in spite of the high molar mass of the dendritic polymer. The excellent processability and potential high reactivity of dendritic polymers makes them extremely promising for thermoset applications, and coatings.

  本文公开了由层状材料和树枝状聚合物形成的互化物和剥落物，以及这些材料的用途，例如用于生产复合材料。分层材料在树枝状聚合物基质（超支化聚合物、星形聚合物或星形支化聚合物）中的分散或在现有技术中尚未公开。树枝状聚合物每个分子的末端基团数量较多，再加上其独特的球状结构，因此在层状硅酸盐中插层时，尽管树枝状聚合物的摩尔质量较高，但其细胞间距较大，特别容易剥离。树枝状聚合物具有出色的可加工性和潜在的高反应活性，因此在热固性应用和涂料领域极具发展前景。
