摘要： A method of reclaiming styrene from polystyrene-containing materials contaminated with animal fats and/or vegetable oils. A solution of polystyrene from such materials in a solvent is heated in distillation equipment to depolymerize the polystyrene and produce a styrene fraction and a heavier fraction, the styrene fraction being separated from the heavier fraction. Prior to heating, an inert gas is used to purge the distillation equipment of oxygen. The method preferably is carried out at the lowest temperature which will achieve the desired rate of depolymerization.

摘要： Monomeric styrene is recovered from plastics waste containing styrene polymers by thermal depolymerization by a process in which the waste is transported in liquid or solid form into a fluidized bed of a solid heat transfer agent and is cracked or depolymerized in an average residence time of less than 60 seconds and styrene is obtained from the gaseous crack products. Preferably, magnesium aluminum silicate is used as a heat transfer agent and C.sub.1 -C.sub.6 -hydrocarbons formed as byproducts in the depolymerization are used as operating gas for maintaining the fluidized bed and are circulated.
