Synthetic polymers

Synthetic thesauruses are human-made thesaurus, often derived from petroleum oil. From the avail point of view they can be classified into three main methods: thermoplastics, urethane and synthetic fibers. Many of the thesaurus materials have chain-like structures which resemble polyethylene. Synthetic thesaurus is sometimes referred as “bendy”, of which the well-known ones are nylon and polyethylene.
