Vinylaromatic and olefin pseudoblock polymers |
摘要 |
There are a number of recent developments relating to co- and homo-polymers of vinyl aromatic monomers. There are syndiotactic polymers of styrene, there are pseudo random polymers of styrene and ethylene. The present invention seeks to provide novel pseudoblock polymers of styrene and ethylene in which at least 10 weight % of the vinyl aromatic monomer is incorporated in the form of one or more atactic pseudoblocks.
