Processes for recycling polystyrene waste and/or polystyrene copolymer waste

Abstract

There are provided processes for recycling waste such as polystyrene thermoplastic polymer waste and/or polystyrene thermoplastic copolymer waste as well as recycled polystyrene thermoplastic polymer and/or recycled thermoplastic copolymer that may, for example, be obtained from such processes. The recycled polystyrene and/or recycled polystyrene copolymer obtained therefrom has a transmittance ranging from 80 to 99%; the transmittance being measured in a UV-VIS spectrum at 600 nm at 20° C. on solution comprising the recycled polystyrene and/or recycled polystyrene copolymer diluted in cymene, and wherein the reference solution for 100% of transmittance in a UV-VIS spectrum at 600 nm at 20° C. is a solution of virgin polystyrene homopolymer diluted in cymene, wherein the content of virgin polystyrene is 20 wt. % of the total weight of the reference solution, wherein the content of recycled polystyrene and/or recycled polystyrene copolymer is 20 wt. % of the total weight of the solution.
