Most butadiene is used to make synthetic rubbers for the manufacture of tyres, grommets and elastic bands. The conversion of butadiene to synthetic rubbers is called polymerization, a process by which small molecules (monomers) are linked to make large ones (polymers). The mere polymerization of butadiene gives polybutadiene, which is a very soft, almost liquid material. The polymerizatio…
