| 摘要 |
<p>The present invention provides a catalyst component comprising a vanadium compound supported on a porous polymer having a porosity (mercury) higher than 0.02 cc/g. With the above catalyst components it is possible to prepare elastomeric copolymers of ethylene with α-olefins CH2=CHR, optionally containing minor proportions of a diene, without fouling problems.</p> |
