Method for producing carboxylated ethylene polymer blends

process for the manufacture of carboxylated ethylene polymer blends by in a 1st stage in a Fluidmischraktor on 100 parts by mass of ethylene under (HDPE, LDPE) and / or linear ethylene copolymers with 2 to ≦ 20 Mass% polymerized C3- To C12Olefin (LLDPE, EOP) selected particulate ethylene polymer having a melt flow rate MFR (190 ° C / 2.16 kg) ≧ 20 g / 10 min 0.05 to 15 Parts by weight of an α, β-ethylenically unsaturated Mono- and / or dicarboxylic acid or its anhydride (carboxyl monomer) or at least one carboxylic monomer containing monomer and 0.01 to 10 parts by mass of a radical initiator or Initiator mixture and added at reaction temperatures between 30 and 120 ° C for a reaction time between 5 and 120 min, and then graft-polymerized in a 2nd stage, a mixture of 100 parts of the Mass in the first solid-phase stage obtained modified ethylene polymer, 150-4000 parts by mass a a melt flow rate MFR (190 ° C / 2.16 kg) having <20 g / 10 min Ethylene polymer or -polymerblends and 0 to 4000 parts by mass an olefinic elastomer continuously a reaction extruder fed, at temperatures of between 160 ° and 260 ° C implemented and a carboxylation between 0.05 and 1 Mass% owning graft ethylene polymer blend continuously is discharged. The products obtained are particularly suitable as adhesion promoters and / or adhesives for different documents, ...
