Abstract: A composition including a copolymer containing polyamide blocks and polyether blocks including at least one carboxylic acid chain end having reacted with an epoxide function, the process for preparing same, and also the use thereof. A foam formed from this composition, the process for preparing same, and the use thereof.

Abstract: The present invention relates to a copolymer having polyamide blocks and having polyether blocks (PEBA) which can be used for the manufacture of an article, preferably a foamed article. The invention also relates to expanded particles prepared from said copolymer and to the manufacture of a foamed article from said expanded particles.

Abstract: The present invention relates to a foamable composition comprising an ethylene-vinyl acetate (EVA) copolymer and for a copolymer of ethylene and of alkyl (meth)acrylate and a branched copolymer containing polyamide blocks and polyether blocks, to a process for producing said composition and to the use of said composition. The present invention also relates to a foam, to a process for producing said foam and to the use of said foam.

Abstract: The present invention relates to a foam of polymers comprising an ethylene-vinyl acetate (EVA) copolymer and/or a copolymer of ethylene and of alkyl (meth)acrylate and a copolymer containing polyamide blocks and polyether blocks (PEBA). The present invention also relates to a process for producing such a foam and also to the use of said foam, in particular in shoes.

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.
