Abstract: The present invention concerns the use of PCL in preparing a block copolymer comprising at least one rigid block and at least one flexible block, for enhancing the sebum resistance of said block copolymer.
The present invention also provides a sebum-resistant block copolymer, characterized in that it comprises rigid blocks and flexible blocks comprising at least 50% by weight of PCL, based on the total weight of flexible blocks, which represents 100%; a process for synthesizing said copolymer; and also compositions and articles comprising a sebum-resistant copolymer of this kind.
