Something seems to have been missed here: the word ‘vulcanised’. Vulcanised rubber (of whatever kind) CANNOT be dissolved in ANYTHING, unless you
devulcanise them first. Rubbers based on sulphur based vulcanisation methods can be devulcanised (the sulphur bearing crosslinks split), but other
types of vulcanisates (like peroxide based systems) resist devulcanisation almost 100 %. But devulcanising sulphur based vulcanisates is messy and
requires chemistry, not mere dissolution.
Vulcanised rubbers belong to the class of ‘thermoset materials’ (like the mother of all: Bakelite) and are essentially one large macromolecule:
all polymer chains being interlinked with each other by means of so-called crosslinks.
Sulphur ‘cured’ rubbers include: NR, IR, IIR, SBR, CR, NBR, most types of EPDM (EPR), polysulphide and a few others. Most other synthetic
elastomers are cured with irreversible means: peroxides and a small army of propriety chemical packages.
Trust me, I was a rubber technologist for about 15 years.
