The present invention relates to thermoplastic hydrophilic polymeric compositions for making a liquid impermeable moisture vapour permeable structure, for example by forming the composition into a layer or film. The thermoplastic compositions comprise preferred thermoplastic polymers and suitable compatible plasticisers having a preferred resistance to extraction by water or aqueous fluids. The layers made from the thermoplastic hydrophilic polymeric compositions of the present invention can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.
L'invention concerne des compositions polymères hydrophiles thermoplastiques permettant de produire une structure imperméable aux liquides mais perméable à la vapeur d'eau, par exemple des couches ou des films. Ces compositions thermoplastiques comprennent des polymères thermoplastiques préférés ainsi que des plastifiants compatibles adéquats présentant un degré de résistance préféré à l'extraction par l'eau ou par des fluides aqueux. Les couches produites à partir de ces compositions polymères hydrophiles thermoplastiques ont diverses applications dans lesquelles l'imperméabilité aux liquides et la perméabilité à la vapeur d'eau sont souhaitables.
