Claim 17:
18. A method for continuously treating polystyrene material comprising:
selecting a solid recycled polystyrene material;
heating said solid recycled polystyrene material in an extruder to create a molten polystyrene material;
placing a first amount of said molten polystyrene material through a chemical depolymerization process in a first reactor to create a first depolymerized polystyrene material;
placing a second amount of said molten polystyrene material through a chemical depolymerization process in a second reactor to create a second depolymerized polystyrene material; and
placing a third amount of said molten polystyrene material through a chemical depolymerization process in a third reactor to create a third depolymerized polystyrene material,
wherein said first reactor, said second reactor, and third reactor are connected in parallel,
wherein said second reactor has a second dimension and said third reactor has a third dimension,
wherein said second dimension and said third dimension differ such that said second depolymerized polystyrene material is different from said third depolymerized polystyrene material; and
grafting a copolymer/monomer onto one of said first depolymerized polystyrene material, said second depolymerized polystyrene material and/or said third depolymerized polystyrene material to create a grafted product,
wherein said copolymer/monomer comprises a functional group.
