Document Type and Number:

WIPO Patent Application WO/2022/071650

Kind Code:

A1

Abstract:

The present invention relates to a technique for recovering a solvent and an unreacted material in an extruder (finisher) for a polyolefin elastomer (POE) preparation process, wherein the solvent and the unreacted material are maximally recovered with energy minimization through a recovery process of hydrocarbons (HCs) removed from a product in the extruder (finisher) for the POE preparation process, and thus are reused in the polyolefin elastomer preparation process.
