Abstract
PURPOSE: A process for recovering atactic polymerby separating atactic polymer which is a by-product of polymerization process of propylene and dissolving in liquid propylene, from propylene under pressure, by which propylene can be liquified again and recycled to the polymerization process without use of compressor.
