CPC classification number: C08J11/20 , C08J2300/30
Abstract: The present invention relates to a process for extracting polymers, preferably polyolefins, from polymer-containing waste material comprising the steps of: providing polymer-containing waste material comprising polyolefin material; contacting the polymer-containing waste material with a non-polar solvent (8) comprising at least one hydrocarbon, optionally halogenated hydrocarbon, having from 4 to 10 carbon atoms, to form a composition (C); heating the composition (C) at a dissolution temperature (T) in the range of 135 to 200° C. and a pressure (P) in the range of 0.1 to 5 MPa for a period of from 5 min to 5 h (M), to obtain a solution comprising the solvent (S) and the polyolefin material dissolved in the solvent (S), and an undissolved material (U); separating the undissolved material (U) from the solution; separating the polyolefin material from the solution, and optionally separating the solvent (S) from the solution.
