Organic chemistry
Since the invention of the first synthetic polymer product, bakelite, synthetic polymer products have frequently been invented.
Kraton (polymer)
Kraton is the trade name given to a number of high performance elastomers manufactured by Kraton Polymers (), and used as synthetic replacements for rubber. Kraton polymers offers many of the properties of natural rubber, such as flexibility, high traction, and sealing abilities, but with increased resistance to heat, weathering, and chemicals. It was first made by the chemical division of the Shell Oil Company in the 1950s, under the technical leadership of Norman R. Legge. Shell sold its Kraton polymers business to private equity firm Ripplewood Holdings in March 2001.
