Polydispersity index from linear viscoelastic data: unimodal and bimodal linear polymer melts

Abstract

This article describes a method for determining the polydispersity index I p2 =

Hydrocarbon polymer analysis by external MALDI fourier transform and reflectron time of flight mass spectrometry

“…It is of interest also to point out that the polymers in Figures 2 and 3 display two maxima regions in the distributions. These are referred to as bimodal distributions as opposed to the usually observed unimodal distributions as in Figure 1, for example [22][23][24][25]. Of the current polymer samples, polystyrene spectra were the easiest to obtain followed in difficulty by polyisoprene, then polybutadiene.…”

Dependence of in vitro fatigue properties of PMMA bone cement on the polydispersity index of its powder

“…Many physical properties of a polymer are strongly related to its molecular weight distribution (MWD) (Llorens et al, 2003). Two features of PDI are to be noted.…”

Synthesis and structural characterisation of tetrahedral zinc(II) and trigonal bipyramidal cadmium(II) complexes containing N′-cyclohexyl substituted N,N-bispyrazolyl ligand

“…The PDI range was slightly narrow when the molecular weight of PMMA increased. These results are explained by the narrower PDI range of the highermolecular-weight polymer [63,64].…”
