Claims (6)

1. Способ предотвращения обрастания в реакторах с циркуляцией, в которых альфа-олефины полимеризуются в виде частиц в присутствии катализаторов, отличающийся тем, что для того, чтобы предотвратить обрастание в реакторе с циркуляцией, в реактор вводится композиция сополимеров альфа-олефина с акрилонитрилом и полимерных полиаминов.
2. Способ по п. 1, отличающийся тем, что указанный полиамин является продуктом полимеризации алифатического первичного моно- или диамина с эпихлоргидрином или сополимером альфа-олефина с малеиновым ангидридом.
3. Способ по п. 1 или 2, отличающийся тем, что отношение сополимера альфа-олефина с акрилонитрилом к полиаминному компоненту составляет от 1: 99 до 99: 1, предпочтительно, от 25: 75 до 75: 25.
4. Способ по пп. 1-3, отличающийся тем, что количество указанной композиции составляет 0,001-3 г/г катализатора, предпочтительно, 0,01-0,7 г/г катализатора.
5. Способ по пп. 1-4, отличающийся тем, что указанный альфа-олефин, полимеризующийся в указанном реакторе, выбирается из группы, состоящей из этилена, пропилена, 1-бутена, 1-гексена или их смесей.
6. Композиция сополимеров альфа-олефина с акрилонитрилом и полимерных полиаминов для использования в качестве предотвращающего обрастание агента в реакторах с циркуляцией.
