Figure 5.31 Van-Gurp Palmen plot (loss angle versus magnitude of complex modulus) of data for linear (circles), star-branched (triangles), and comb (squares) polymers prepared by the hydrogenation of anionically polymerized polybutadienes.The branching structure hasadistinct effect on the shape of the curve. From Lohse etal. [119].

For a polyolefin sample, a test of the tTS for its linear viscoelastic data is also helpful to examine the existence of long branches. (This test can be made through sensitive plots such as the Han plot and/or van Gurp-Palmen plot explained earlier. For star-branched and multibranched polyole-...
