Metallocene ethylene-hexene
copolymer
The copolymers of ethylene and *-hexene were prepared with
half-metallocene titanium complex
The initial concentrations of *-hexene were varied to investigate
how the different amounts of co monomer affect on the catalytic
activity of copolymerization system and Microstructure of the
copolymers. It has been found that this catalytic system was not
active for hexene polymerization,However, it can be active when
ethylene was introduced to perform ethylene-hexene
copolymerization. As co monomer, *-hexene provides positive co
monomer effect on the system although very high concen ration of
*-hexene was introduced. However, the microstructures of the
obtained copolymers, which were examined by *3C-NMR, need to be
improved
Because with highly alternating sequence distribution of co monomer
causing them losing some essential specific thermal properties.
