PROCESS FOR MODIFYING THERMOPLASTIC POLYMERS
A process for modifying thermoplastic polymers by carrying out multiple sequential reactions in a single reactor. It comprises: a) introducing a polymer composition into an extruder reactor; b) passing said polymer composition (free of solvents or diluents) into a reaction zone in which said polymer...

| description | A process for modifying thermoplastic polymers by carrying out multiple sequential reactions in a single reactor. It comprises: a) introducing a polymer composition into an extruder reactor; b) passing said polymer composition (free of solvents or diluents) into a reaction zone in which said polymer composition undergoes multiple sequential reactions, whilst this reaction zone comprises two vents preventing loss of reagents through the reaction zone; c) passing the polymer composition into a purification zone wherein the impurities formed in the preceding step are eliminated or said impurities are neutralised by subjecting said polymer composition to pressure which is lower than the atmospheric pressure, whilst this reaction zone contains at least two vent zones; d) passing said polymer composition from said purification zone into a second reaction zone and repeating the preceding two steps once at least in the consecutive two zones until each of the consecutive reaction is ended; and passing the polymer composition through the rest of the extruding process. |
