| description | A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder (10) is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section (12) of the modified planetary roller extruder (10), conveying the raw materials from the feeding section (12) to a compounding section (14) of the modified planetary roller extruder (10), continuously mixing the primary raw materials in the compounding section (14) to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section (14) of the modified planetary roller extruder (10) includes a main spindle (26) surrounded by and intermeshed with a plurality of planetary spindles (28, 30) at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights. |
