It is manufactured from petroleum or natural gas. Various types of synthetic rubbers include butadiene rubber, styrene-butadiene rubber, neoprene, polysulfide rubbers (Thiokol's), butyl rubber, and ...
Researchers' new polymer strategy shifts a centuries-old engineering paradigm with a molecular design that doesn't sacrifice stretchability for stiffness.
Polymers are either natural or synthetic macromolecules composed of many repeating units (monomers) usually arranged in the form of a chain. Examples of polymers are silk, rubber, silicone, DNA ...
