Three commercial LLDPE samples with ethyl, hexyl and isobutyl branches were fractioned by cross chromatographic fractionation methods, i.e. a combination of SEC and TREF techniques. The fractions with different molecular weight distribution (MWD) and short chain branching distribution (SCB) were obt
In the present publication, a method to identify and distinguish between different types of low-density polyethylene based on thermal fractionation and FTIR analysis is described. It was shown that during thermal fractionation four to seven endothermic peaks are obtained as opposed to one or two pea
