Development of PVC/Silica Hybrids Using PVC Plastisols

A novel method for producing a plasticised PVC with increased porosity has been developed, by the use of an organic‐inorganic hybrid. Silica was produced in situ from tetraethoxysilane via a hydrolytic sol‐gel processing route. Tetrahydrofuran was used as co‐solvent, and γ‐glycidyloxypropyl‐trimetho...

description A novel method for producing a plasticised PVC with increased porosity has been developed, by the use of an organic‐inorganic hybrid. Silica was produced in situ from tetraethoxysilane via a hydrolytic sol‐gel processing route. Tetrahydrofuran was used as co‐solvent, and γ‐glycidyloxypropyl‐trimethoxysilane as coupling agent. The films produced were transparent, with moderate mechanical properties. A film containing 20% silica showed a 45% increase in water vapour permeability.
