Abstract

Гомо- и сополимеры этилена, обладающие очень высокой молекулярной массой и узким молекулярно-массовым распределением, можно получать путем осуществления реакции полимеризации в присутствии катализатора на основе металлоцена, в котором металлоцен является пространственно жестким и находится по существу в своей мезо-изомерной форме.
