CONTINUOUS PROCESS FOR PRODUCTION OF SILICONE PRESSURE SENSITIVE ADHESIVES
摘要
<p>A composition for preparing a pressure sensitive adhesive contains (A) a hydroxyl-functional polydiorganosiloxane polymer, (B) a hydroxyl-functional polyorganosiloxane resin, and (C) a solvent. A continuous method for producing the silicone pressure sensitive adhesive is performed by mixing the composition while heating the composition at a temperature above the vaporization point of the solvent and removing essentially all volatile species in an apparatus with a residence time sufficient for bodying ingredients (A) and (B). A devolatilizing twin-screw extruder is useful in the method.</p>
