Abstract

Настоящее изобретение относится к новому способу приготовления катализатора Циглера-Натта, обладающего повышенной активностью в процессе высокотемпературной гомо- и сополимеризации этилена с альфа-олефинами в растворе. Способ включает смешение и нагревание компонентов катализатора, приводящее к значительному увеличению активности катализатора, приблизительно на 60%.
