Abstract: A polymer composition, especially used for manufacturing screw caps intended for drinks bottles, which are easy to unscrew and at the same time avoid transmitting a taste and/or a smell to the drinks contained in the bottles. The composition includes (1) a polymer, except a polymer based on a conjugated diene, (2) at least one stabilizer and (3) at least one additive in an amount form 0.01 to 1% by weight, chosen from (a) natural, modified or refined, lignite waxes or montan waxes, (b) polyolefin-based or paraffin-based polar waxes, and (c) refractory or metal oxides grafted by polar organic compounds.
