海报摘要

The molecular structure of polyolefins copolymers is important for the research and development of polyolefins. The chemical composition distribution of polyolefins copolymers synthesized by different catalytic systems and varying comonomer types was studied using high-temperature size exclusion chromatography (HT-SEC) coupled with a new model of an infrared detector (model IR5, PolymerChar, Valencia, Spain). The IR5 detector enables monitoring of the IR response of methyl (-CH3) and methylene groups (-CH2-) in macromolecules with high sensitivity. We have investigated the dependence of the CH3/CH2 ratio along the molar mass axis for the series of ethylene/1-alkene copolymers.
