SOLID STATE DEVOLATILIZATION OF SYNDIOTACTIC VINYL AROMATIC POLYMERS WITH CATALYST DEACTIVATION

摘要

The present invention is an improved solid state polymer devolatilization process which comprises heating a wet feed mixture comprising polymer, residual monomer(s), process solvents and active catalyst residues in the presence of an inert gas, wherein the improvement comprises replacing the inert gas with a catalyst desactivating gas.
