Coordination polymerization of styrene monomer |
摘要 |
<p>A process for preparing improved yields of styrene polymers by means of polymerization with a coordination type polymerization catalyst wherein the styrene monomer is first contacted with a hydrogenating agent under hydrogenation conditions such that substantially all phenylacetylene contained in the monomer stream is hydrogenated and thereafter contacting with a coordination polymerization catalyst.</p> |
