"vulcanization" is so named because the original natural rubber product is crosslinked using sulfur as a crosslinking agent, and with the development of the rubber industry, crosslinking can be performed using a variety of non-sulfur crosslinking agents. The more scientific meaning of vulcanization is therefore "crosslinking" or "bridging", i.e. the process of forming a network of macromolecules by crosslinking linear macromolecules.
