Title:
METHOD FOR RECOVERING STYRENE MONOMER FROM IMPACT- RESISTANT POLYSTYRENE
Document Type and Number:
Japanese Patent JP2001288124
Kind Code:
A
Abstract:
To provide a method for recovering styrene monomer from impact- resistant polystyrene, in which the industrially useful styrene monomer can be recovered in a high yield and in a high purity from the impact-resistant polystyrene wastes whose effective recycling method has not been established.
This method for recovering the styrene monomer from the impact-resistant polystyrene is characterized by its thermal decomposition, use of a metal sulfate and/or manganese dioxide as a catalyst.
