Nucleation process for inducing crystallization in poly(alpha olefins)

摘要

The present invention relates to a process for nucleating olefin polymers prepared with high activity MgCl.sub.2 -supported Ti procatalysts and aluminum alkyl cocatalysts, the process involving heat treating the olefin polymers after polymerization and before melt compounding with an alcoholic solution of an aromatic carboxylic acid.
