 note = {We examined the dissolution of polystyrene into p-cymene and related substances, in order to
develop an alternative method for the recycling of expanded polystyrene. The dissolving power
of p-cymene (212.0 g [100 g solvent ]-1) to polystyrene at 50?C compared favorably with those
of 2-p-cymenol (156.7 g [100 g solvent ]-1), (R)-limonene and its structural isomers
(181.7-197.1 g [100 g solvent ]-1) and Abies leaf oil (84.7 g [100 g solvent ]-1). The favorable
solubility of polystyrene into p-cymene can be explained by the solubility parameter.
p-Cymene and polystyrene can be recovered almost quantitatively from the polystyrene
solution by simple steam distillation.},
