    Abstract: The present invention relates to a non-crosslinked block copolymer foam composition, characterised in that it is in the form of a polymer matrix comprising closed cells containing gas, said matrix comprising: from 90 to 99.9% by weight of said block copolymer; and from 0.01 to 10% by weight of metal carbonate, for the total weight of the foam composition. The present invention also relates to a foamable composition and a method for manufacturing said foam, as well as the use of the foam in sports shoe soles, balloons or balls, gloves, personal protection equipment, rail soles, automobile parts, construction parts, electrical and electronic equipment parts, audio equipment, sound- and/or heat-proofing, and parts used to damp vibrations.

    Abstract: The present invention relates to an extrudable polymer composition comprising: 99.5 to 99.95% of at least one hard-soft block copolymer comprising: at least 25% by weight of soft block polyethylene glycol (PEG) with functionality equal to 2, with respect to the total weight in copolymer; from 0.05 to 0.5% by weight of at least one polyol comprising at least three hydroxyl groups, with respect to the total weight of the composition; characterised in that: the weight-average molecular mass of said copolymer is at least equal to 100,000 g/mol; and the weight-average molecular mass of the polyol is at least equal to 1000 g/mol; and said at least one polyol binding hard copolymer blocks by ester bonds. This invention relates in particular to the use of said composition in extrusion processes for manufacturing vapour-permeable objects.
