Abstract
The invention relates to a flexible composition comprising a vinyl chloride polymer and a block copolymer. The latter comprises a poly(ethylene oxide) block and a block of a polymer which is miscible with the vinyl chloride polymer, other than the latter itself. The invention also relates to a poly(ethylene oxide)/poly-.epsilon.-caprolactone diblock copolymer which can be used in this composition, as well as to the use of this composition for the manufacture of an article and to an article comprising this composition.
