Study on Crystalline Methylene Sequence Length of High Density Polyethylene via Thermal Fractionation
High density polyethylene (HDPE) is generally produced through the copolymerization of ethylene and comonomers such as hexene or octene, which generates butyl or hexyl branches, respectively, and the branches interrupt the ethylene sequence...
