Goodyear's discovery ……………
In 1844, Charles Goodyear was working on ways of making rubber resistant to heat and cold when he accidentally dropped rubber mixed with sulphur on a hot stove. The result, which Goodyear named vulcanised rubber, was what he had been seeking. Although Goodyear patented vulcanisation and other ways to improve rubber, other people constantly violated his patents and he died in poverty.
