Abstract: A pressure-sensitive adhesive having good adhesive and flame retardancy properties is provided. The pressure-sensitive adhesive comprises: (A) at least one poly(meth)acrylate and (B) at least one organophosphorus compound, wherein the monomer composition forming the basis for the poly(meth)acrylate comprises (i) at least one (meth)acrylic ester whose alcohol component contains more than 4 carbons; (ii) at least one (meth)acrylic ester whose alcohol component contains not more than 4 carbons; and (iii) acrylic acid and/or methacrylic acid at a total of at least 5 wt %. Also provided is a method of using the pressure-sensitive adhesive as a flame-retardant pressure-sensitive adhesive.

Abstract: A process for the continuous and solvent-free production of a pressure-sensitive adhesive based on solid EPDM rubber, the pressure-sensitive adhesive produced thereby, and an adhesive tape containing the pressure-sensitive adhesive. The pressure-sensitive adhesive is produced in a continuously operating assembly in the form of a planetary roller extruder having a filling section and a compounding section, the compounding section consisting of at least two coupled roller cylinders, by a) feeding the solid EPDM rubber and any further components into the filling section of the planetary roller extruder, b) transferring the components from the filling section into the compounding section, c) adding liquid EPDM rubber, plasticizer, tackifier resin, and any further components to the compounding section, and d) discharging the resultant pressure-sensitive adhesive, which process comprises feeding the solid EPDM rubber as a melt into the filling section.
