Abstract:
Comonomer reactivity ratios for ethylene copolymerization with propylene, butene-1 and hexene-1 over new high activity supported Ziegler catalysts and TiCl3 have been determined. It has been established that copolymerization reactivity of the catalysts decreases in the sequence: VCl4/MgCl2>δTiCl3 · 0.3 AlCl3>TiCl4/MgCl2. Copolymer density is practically independent of catalyst composition and controlled by the concentration and type of α-olefins. The catalysts examined are more active in copolymerization than in the homopolymerization of ethylene.
Определены константы сополимеризации этилена с пропиленом, бутеном-1 и гексеном-1 на новых высокоактивных нанесенных катализаторах циглеровского типа и на треххлористом титане; показано, что сополимеризующая способность снижается в ряду катализаторов: VCl4/MgCl2> δ-TiCl3·0,3AlCl3>TiCl4/MgCl2. Плотность сополимера практически не зависит от состава катализатора, а определяется содержанием и типом α-олефина. Активность исследуемых катализаторов в процессе сополимеризации выше, чем при гомополимеризации этилена.
