Estimating the term…
The present application relates to an ethylene/α-olefin copolymer with high light transmittance, which meets conditions (a) to (d) below: (a) a density is 0.855-0.885 g/cm3; (b) a molecular weight distribution is 1.8-3.2; (c) a melt index is 0.3-40 g/10 min at 190° C. and a load of 2.16 kg; and (d) an ethylene ternary sequence EEE has a proportion of less than 70%, and EXE+XEX has a proportion of more than 10%, calculated through high-temperature 13C nuclear magnetic resonance spectra (13C-NMR); wherein E represents an ethylene unit, and X represents an α-olefin unit. The ethylene/α-olefin copolymer of the present application has a low glass transition temperature and high light transmittance, which can be used as a photovoltaic packaging material.
An ethylene/α-olefin copolymer, comprising an ethylene ternary sequence EEE by a proportion of less than 70%, and EXE+XEX by a proportion of more than 10%, calculated through 13C nuclear magnetic resonance spectra;
