Abstract
Silicone pressure sensitive adhesive (PSA) compositions and methods for their preparation are provided. In one embodiment, PSAs are formed from a silicone polymer mixture by condensation polymerization of low viscosity polyorganosiloxanes in inert solvents and/or silicone fluids, and optionally adding a silicone resin (MQ) during polymerization. The silicone polymer mixture formed may also be mixed with a silicone resin (MQ) and bodying catalyst, and bodying is allowed to continue until the desired reaction product is formed.
