Properties of synthetic rubber
The secret to the success of synthetic rubber is in the structure of its chain of molecules: two hard ends on the outside (Styrene), a flexible, softer, rubbery middle part (Butadiene).So the structure is: Styrene – Butadiene – Styrene = SBS.That looks a little bit like a skipping rope with extra long handles.

Natural Rubber and Synthetic Rubber Preparation and Properties
Preparation of Natural Rubber: To enhance all these properties, sulphur is added to the rubber and it is heated at a temperature ranging 373 k to 415 k. This process is known as vulcanization. Sulphur acts as a cross-linking agent and after vulcanization, rubber gets cross-linked and becomes hard.

31.5: Natural and Synthetic Rubbers - Chemistry LibreTexts
Synthetic Rubber. The most important synthetic rubber is Neoprene which is produced by the polymerization of 2-chloro-1,3-butadiene. In this illustration, the dashed lines represent repetition of the same base units, so both the products and reactants are polymers. The reaction proceeds with a mechanism similar to the Friedel-Crafts mechanism.

Growth and production of rubber - Ghent University
Currently, natural rubber on the world market is competed by synthetic rubber, which is derived from oil products. 1. Introduction Rubber (Hevea brasiliensis) is a fast-growing upright tropical tree crop which is mainly cultivated for its production of latex, a milky plant liquid, which serves as a basis for various rubber products.

Rubber: A simple introduction - Explain that Stuff
Today, most natural rubber still comes from the Far East, while Russia and its former republics, France, Germany, and the United States are among the world's leading producers of synthetic rubber. The world's largest single source of latex rubber is the Harbel Rubber Plantation near Monrovia in Liberia, established in the 1920s and 1930s by the Firestone tire company.

A synthetic rubber is any artificial elastomer. These are mainly polymers synthesized from petroleum byproducts. About fifteen billion kilograms of rubbers are produced annually, and of that amount two thirds are synthetic. Global revenues generated with synthetic rubbers are likely to rise to approximately US$56 billion in 2020. Synthetic rubber, like natural rubber, has uses in the automotive industry for tires, door and window profiles, hoses, belts, matting, and flooring.

The Manufacturing Process of Rubber | Sciencing
The natural rubber manufacturing process begins with harvesting latex from rubber trees. Harvesting latex from rubber trees starts with scoring or cutting into the bark of the tree. Latex flows into a cup attached to the bottom of the cut in the tree. The latex material from many trees is accumulated in large tanks.
