摘要
Amorphous polymers of alpha-olefins, in particular of propylene, having high molecular weights and molecular weight distributions can be obtained, in which the isotactic sequences are more abundant than syndiotactic ones, with high yields at temperatures of industrial interest all carried out. polymerization reaction in the presence of metallocene catalysts comprising particulate bridge bis-indenyl compounds substituted at position 3 in the indenyl groups. The amorphous polymers obtained are particularly useful in the preparation of compositions that are miscible with substantially isotactic alpha-olefins.
