“…That occurs when a large number of topological constraints, other than chemical crosslinking linked to vulcanization, disrupt the ideality of the network 25. The nature of topological constraints always gives rise to debate, and the articles by Boyer and Miller26 and more recently Sherbakov and Grishin27 review this aspect. They involve either entanglement between macromolecules or physical crosslinks (van der Waals forces, etc.)…”

“…The short T 2 were attributed to the influence of physically or chemically crosslinked chains, medium T 2 representing chains ends or defects effects and the long relaxation times corresponding to very mobile molecules as in the sol fraction. The molecular weight between entanglements, M e , of cis‐trans polybutadiene is indicated in the literatures as equal to 4600 g/mol30, 31 that we consider as the M e value of our polymer despite the presence of OH groups in chain‐ends. Accordingly, GPC results reported on Figure 2 shows that the proportion of entangled chains in the HTPB is of about 36%.…”
