WebPolymers. The word “Polymer” is derived from two Greek words, ‘Poly’ that means many (numerous) and ‘Mer’ which means units. In basic terms, a polymer is a long-chain molecule that is composed of a large number of repeating units of identical structure. These identical structures, we understand as a unit made up of two or more molecules, join together to … WebDec 13, 2024 · 1. This answer by @andselisk may be relevant. I think disulfur dichloride would dissolve latex, maybe slowly, but it is a chemical weapons precursor, and not something to flush down a drain anyway. An ordinary sodium hydroxide/Al/sodium nitrate drain cleaner, e.g., “Drano” in the USA, generates lots of heat, is extremely caustic, and ...

Rubber is a natural polymer of isoprene (polyisoprene), and an elastomer (a stretchy polymer). Polymers are simply chains of molecules that can be linked together. Rubber is one of the few naturally occurring polymers and prized for its high stretch ratio, resilience, and water-proof properties.
