CATIONIC POLYMERISATION OF 1-OLEFINS |
摘要 |
Case7667(2) CATIONIC POLYMERISATION OF 1-OLEFINS This invention relates to a process for producing a polymer predominating in terminal unsaturation by cationically polymerising a 1-olefin in the liquid phase at a temperature from -100 to +100.degree.C in the presence of a catalyst composition comprising tin tetrachloride and a co-catalyst which is a source of cations and which is substantially free of organometallic compounds. The process is particularly suited to producing polybutenes having high vinylidene content which have high reactivity, especially towards forming maleic anhydride adducts.
