摘要

A range of crystalline copolymers of ethylene with a-olefins (propene, hexene, octene and octadecene) were prepared using the complexes Et(Ind)_2ZrCl_2 and (nBuCp)_2ZrCl_2 activated with MAO. The average composition of the copolymers was measured using ~1H- and ~(13)C-NMR. Then the samples were characterized by High Temperature SEC and DSC. These investigations showed that polymers are homogeneous in composition and consequently were suitable to be used as standards for TREF. This work provided calibrations curves for TREF that can be used on a wide range of a-olefin contents. Finally, these calibrations curves were used to characterize heterogeneous copolymers of ethylene/hexene synthesized using a conventional Ziegler-Natta catalyst.
