ABSTRACT:
Pressure sensitive adhesives (PSA) having a reduced volatile fraction content are provided by a process which comprises extracting a cured PSA with a fluid in or near its supercritical state. The process provides PSAs and articles containing PSAs which meet the volatility requirements of ASTM E-595. A silicone PSA transfer film having utility in outer space is obtained.
