    摘要: 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 selected thermoplastic polymers and selected compatible plasticiser that provide the thermoplastic hydrophilic composition with a desired tackiness level, without impairing the moisture vapour permeability of films or layers made from the thermoplastic hydrophilic polymeric compositions. 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.

    摘要: The present invention relates to liquid impermeable, moisture vapour permeable film or layers comprising thermoplastic hydrophilic polymeric compositions. The thermoplastic compositions comprise selected thermoplastic hydrophilic polymers, selected compatible plasticisers, and selected functionalized copolymers that provide the resulting film or layer with an increased mechanical strength, and better bonding capability to a substrate, without impairing the moisture vapour permeability of said films or layers. The layers and films of the present invention made from the thermoplastic hydrophilic polymeric compositions can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.
