Title: Living random copolymerization of ethene and norbornene using ansa‐fluorenylamidodimethyltitanium complex
Abstract:Abstract Ethene‐norbornene copolymerizations were conducted by ( t ‐BuNMe 2 SiFlu)TiMe 2 ( 1 ) activated with dried methylaluminoxane (MAO) (free from Me 3 Al) at 0°C and 20°C under atmospheric pressu...Abstract Ethene‐norbornene copolymerizations were conducted by ( t ‐BuNMe 2 SiFlu)TiMe 2 ( 1 ) activated with dried methylaluminoxane (MAO) (free from Me 3 Al) at 0°C and 20°C under atmospheric pressure of ethene at various norbornene concentrations. At 0°C and high norbornene concentration, the molecular weight of the copolymer increased linearly against polymerization time while keeping narrow molecular‐weight distribution. The 13 C NMR spectrum revealed that random copolymer with 53 mol‐% of norbornene was obtained. The glass transition temperature was above 150°C.Read More
