Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist [1] [2] and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
Some contest that it was invented by Charles Goodyear in America 1839, and patented in 1844. [11] Other accounts attribute it to Thomas Hancock in Britain in 1843. [12] The first rubber condom was produced in 1855, [13] and by the late 1850s several major rubber companies were mass-producing, among other items, rubber condoms. A main advantage ...
Thomas Hancock patents the vulcanization of rubber in Britain immediately followed by Charles Goodyear in United States. [3] 1856: Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869
A vast array of products are made with vulcanized rubber including ice hockey pucks, tires, shoe soles, hoses and many more. When "rubber fever" struck Boston in the 1830s, there was a large consumer demand for products made of rubber- aprons, life preservers, hats, carriage tops, and, by 1836, waterproof shoes.
The company formerly known as the United States Rubber Company, now Uniroyal, is an American manufacturer of tires and other synthetic rubber-related products, as well as variety of items for military use, such as ammunition, explosives, chemical weapons and operations and maintenance activities (O&MA) at the government-owned contractor-operated facilities.

The qualities of rubber, though fascinating to Goodyear, were highly dependent on temperature: it was tacky when hot, brittle when cold. Vulcanization of rubber tempered its properties so that it was easily molded, durable, and tough. A rubberized elastic webbing made Goodyear's galoshes (c. 1890) easy to pull on and off.
1999: America Online has over 18 million subscribers and is now the biggest internet provider in the country, with higher-than-expected earnings. It acquires MapQuest for $1.1 billion in December.
The company Thiokol applied their name to a competing type of rubber based on ethylene dichloride. [4] In 1935, German chemists synthesized the first of a series of synthetic rubbers known as Buna rubbers. These were copolymers, meaning the polymers were made up from two monomers in alternating sequence.
