ABSTRACT:
A process for preparing improved yields of styrene polymers by means of polymerization with a Ziegler-Natta 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 Ziegler-Natta catalyst.
