  • Polymeric compositions for moisture vapour permeable structures with improved structural stability and structures comprising said compositions
    Publication number: 20040180998
    Abstract: The present invention relates to hydrophilic polymeric compositions for making a liquid impermeable moisture vapour permeable structure, for example by forming the composition into a layer or coating onto a suitable substrate for example a microporous film and to composite structures comprising the compositions. The hydrophilic polymeric compositions of the present invention do not solidify at room temperature, but remain viscous or “creamy”. This prevents layers made from the hydrophilic polymeric composition of the present invention from settling as a film so that delamination of a composite structure comprising the hydrophilic polymeric composition coated into a layer onto a suitable substrate is avoided. The hydrophilic polymeric compositions of he present invention can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.

  • Liquid impermeable, moisture vapour permeable layers and films comprising thermoplastic hydrophilic polymeric compositions and having improved strength
    Publication number: 20030194566
    Abstract: 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.

  • Thermoplastic hydrophilic polymeric compositions for moisture vapour permeable structures
    Publication number: 20030171464
    Abstract: The present invention relates to thermoplastic hydrophilic polymeric compositions for making a liquid impermeable moisture vapor 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 vapor 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 vapor permeability are desirable.
