PROCESS FOR PREPARING STEREOREGULAR POLYMERS |
| 摘要 |
<p>For gas phase polymerization reactions in the presence of an unsupported polymerization catalyst, there is provided a process for introducing a liquid catalyst so as to provide a resin particle lean zone such that the average particle size of the resin produced ranges from 0.25 to 1.52 mm (0.01 to 0.06 inches).</p> |
