Title:
POLYMERIC COMPOSITIONS FOR MOISTURE VAPOUR PERMEABLE STRUCTURES WITH IMPROVED STRUCTURAL STABILITY AND STRUCTURES COMPRISING SAID COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO2004058116
Kind Code:
A3
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.
