A type of plastic made from a chemical called butadiene, often used to create synthetic rubber products.
Polybutadiene is commonly used in the production of tires and other rubber goods.
Polybutadiene → It is formed from "poly-" (from Greek "polus", meaning many) and "butadiene" (a compound name derived from "butane" and "diene", where "butane" refers to a four-carbon alkane and "diene" indicates the presence of two double bonds). The word "polybutadiene" refers to a synthetic rubber made from many butadiene units.
Think of 'many' ('poly-') units of a specific type of compound ('butadiene') coming together to form a material. This helps you remember that polybutadiene is a type of synthetic rubber made from many butadiene molecules.
