ABSTRACT:
The present invention relates to a method of making silicone pressure sensitive adhesive compositions comprising the steps of heating a mixture of a polydiorganosiloxane, a silicone resin copolymer, and an equilibration catalyst, and then adding an organic peroxide or azo compound to the resultant reaction product. The silicone pressure sensitive adhesives prepared by the method of this invention are useful in preparing articles such as pressure sensitive tapes, labels, emblems and other decorative or informational signs.
