英文摘要	To further extend temperature range of application and low temperature performance of the ethylene-styrene copolymers, a series of poly(ethylene-styrene-propylene) samples with varying monomer compositions and relatively low glass-transition temperatures (T-g=-28 - 22 degrees C) were synthesized by Me2Si(Me4Cp)(N-t-Bu)TiCl2/MMAO system. Since the C-13 NMR spectra of the terpolymers were complex and some new resonances were present, 2D-H-1/C-13 heteronuclear single quantum coherence and heteronuclear multiple bond correlation experiments were conducted. A complete C-13 NMR characterization of these terpolymers was performed qualitatively and quantitatively, including chemical shifts, triad sequence distributions, and monomer average sequence lengths.
