  • Charles Goodyear paved the way for mass production of "rubbers" when he patented the vulcanization of rubber in 1843, and they were a mainstay of birth-control efforts until the pill emerged as more dependable and convenient.

    The Birth-Control Riddle

  • Includes discussion of natural polymers from tropical trees and the vulcanization of rubber, semi-synthetics (such as celluloid), thermosetting plastics (such as Bakelite), amino plastics (such as melamine), thermoplastics, and high-tech plastics.


  • The addition of sap to latex begins complex chemical changes that provide a much improved material for tools, figurines and medicines, in a process akin to vulcanization, invented three thousand years later by Charles Goodrich.

  • James Goodyear left rubber on a hot stove overnight and invented vulcanization.

  • Therefore, the more expensive modern latex ulama balls are made by the traditional technique of using boiled rubber sap mixed with other ingredients required for vulcanization.

  • Ancient Mayans used objects made from the sap of the rubber tree in sports and rituals, but latex proved too unstable chemically to be of commercial value until 1839, when American inventor Charles Goodyear discovered the vulcanization process.

    He Hit the Road, Found Rubber

  • With vulcanization, crude natural rubber could be heated and chemically treated to make it not only more stable but also more pliable.

    He Hit the Road, Found Rubber

  • Rubber condoms only became available in the United States after the discovery of vulcanization technology in the 1830s.

    A Crash Course On Contraception

  • But in 1839, Charles Goodyear invented vulcanization, the process that gives rubber its elasticity and bounce, and the Amazon rubber boom was on.
