摘要:
Amorphous polymers of propylene modified with ethylene units are prepared in high yields, by carrying out the polymerization reaction in the presence of a catalyst based on a metallocene compound that has two bridged fluorenyl ligands. These copolymers have glass transition temperatures (T.sub.g) well below 0.degree. C., making it possible for the products manufactured from them to be used at low temperatures.
