  • Patent number: 8552084
    Abstract: A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention is a continuous process that includes introducing primary raw materials comprising a non-thermoplastic elastomer into a planetary roller extruder, introducing a heat-activatable crosslinker into the planetary roller extruder for mixing with the primary raw materials, and compounding the primary raw materials and the heat activatable crosslinker to form an adhesive composition while maintaining the temperature of the adhesive composition between about 25° C. and about 100° C. The non-thermoplastic elastomer is masticated during compounding and at least some of the heat-activatable crosslinker remains generally unactivated and is available for later activation.
