Copolymer

Part of speech: noun

Definitions

1. A type of polymer made by linking together multiple different monomer units, resulting in a distinct material with varied physical and chemical properties
2. This material is generated through the polymerization process of two or more dissimilar monomers, ending up with unique characteristics
3. A polymer formed by chemically joining two or more different monomer types in a chain to create a compound with diverse features

Etymology: "Copolymer" is a plain technical compound, built from the prefix "co-" ("together, jointly") attached to "polymer." The "polymer" part goes back to ancient Greek: "polys" meant "many" and "meros" meant "part," so a polymer is a substance made of many repeated parts. The "co-" prefix, from Latin "con-" (later shortened to "co-"), signals that two different kinds of units are being joined into one chain rather than one unit being repeated. The word is a modern scientific coinage built from these classical pieces, not a term the Greeks or Romans would have recognized. It describes a polymer in which two or more distinct monomers, the small building blocks, are linked together in the same molecular chain. Its meaning is fixed by its parts: "co-" for joint, "poly-" for many, and "-mer" for part.
