Abstract

See full text

This invention relates to an apparatus and method for separating a solvent in a metallocene catalyst-based solution polymerization process for preparing a polyolefin, suitable for use in removing a solvent from a reaction mixture resulting from a polymerization step during a solution polymerization process for preparing a polyolefin polymer using a metallocene catalyst, wherein volatile matter including a solvent and an unreacted monomer is primarily removed from the reaction mixture using a flash drum, after which residual volatile matter including the solvent, which is left behind in the reaction mixture after the primary removal process, is secondarily removed in a high vacuum using a thin-film evaporator. The polymer thus obtained has a volatile matter content of 100 ppm or less and is thus an environmentally friendly product.
