PROCESSES AND APPARATUS FOR CONTINUOUS SOLUTION POLYMERIZATION
摘要
<p>The disclosure provides a plant for the continuous solution polymerization of a feed comprising one or more olefin monomers in a solvent, e.g., hydrocarbon solvent, in which the plant comprises means for separating solvent from the polymer including a flash tank and a vacuum devolatilizer. The plant also includes in a first aspect stabilizer addition means for adding a stabilizer to the concentrated polymer fines at a location downstream of the flash and upstream of the vacuum devolatilizer. In another aspect the plant comprises means to add a molten stabilizer to the polymer at a location downstream of the reactors.</p>
