- Новые диамидоаминовые комплексы циркония общей формулы [(ArNCH2CH2)2NH]ZrBn2 (Bn = CH2Ph), различающиеся числом и положением алкильных заместителей в арильном фрагменте, синтезированы и охарактеризованы методами 1H и 13C ЯМР-спектроскопии. С использованием рентгеноструктурного анализа доказана молекулярная структура этих комплексов. Полученные комплексы исследованы в гомогенной полимеризации этилена и сополимеризации этилена с гексеном-1 при активации модифицированным метилалюмоксаном (MMAO-12). В сополимеризации этилена с гексеном-1 в присутствии H2 комплекс [((1,2,3,4,5,6,7,8-октагидроантрацен-9-ил)NCH2CH2)2NH]ZrBn2 (Zr5) продемонстрировал наиболее выраженный положительный сомономерный эффект; при катализе комплексом [((2,4,6-изо-Pr3C6H2)NCH2CH2)2NH]ZrBn2 (Zr2) была достигнута максимальная степень внедрения гексена-1 в образующийся сополимер1.
