Polymer modification system for vinylaromatic monomer production apparatus |
摘要 |
Disclosed is a process for modifying accumulated cross-linked polymer in an apparatus used for the production of a vinylaromatic compound, comprising optionally softening the polymer with an organic solvent; precipitating the polymer with a light, polar non-solvent for the polymer and expanding the softened polymer by bringing the softened polymer in contact with steam whereby the polymer is converted into a state which enables it to be more easily removed from the apparatus.
