  • Patent number: 6780271
    Abstract: Process for the continuous solvent-free and mastication-free production of self-adhesive compositions based on non-thermoplastic elastomers in a continuously operating apparatus having a filling section and a compounding section, comprising a) feeding the solid components of the self-adhesive composition, such as elastomers and resins, into the filling section of the apparatus, optionally feeding of fillers, colorants and/or crosslinkers, b) transferring the solid components of the self-adhesive composition from the filling section to the compounding section, c) adding the liquid components of the self-adhesive composition, such as plasticizers, crosslinkers and/or further tackifier resins to the compounding section, d) preparing a homogeneous self-adhesive composition in the compounding section, and e) discharging the self-adhesive composition.
