Charles Goodyear Receives Patent for Vulcanized Rubber

Charles Goodyear Receives Patent for Vulcanized Rubber. The "rubber fever" of the early 1830s that had spawned the factory in Roxbury and other towns around Boston cooled almost as quickly as it had heated up. In its natural state, rubber had a fatal flaw: it melted in hot weather and froze in the cold.

Sulfur Vulcanization of Rubbers (polydienes)

Vulcanization of rubber by sulfur alone is extremely slow and can take several hours at elevated temperatures (140°C or more). This is problematic because long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties.
