WebOct 2, 2024 · ν of a vulcanized rubber can be measured using the solvent swelling method (Jovanović et al. 2016; Stojčeva-Radovanović, & Marković, 2001; Stojceva-Radovanovic et al. 2002). A good should be used such that the crosslinked rubber can absorb and swell as much as possible until the retraction forces in the network balance the swelling forces.
Web(b) Vulcanized rubber has a network structure with cross-links. (c) Vulcanized rubber on stretching. The covalent cross-links survive the stretching and help the molecules to spring back once the tension has been relaxed.
