WebApr 8, 2012 · Polyester vs Polyamide. Polymers are large molecules, and have the same structural unit repeating over and over. The repeating units are called monomers. These monomers are bonded to each other with covalent bonds to form a polymer. They have a high molecular weight and consist over 10,000 atoms. WebOct 13, 2024 · Even the DNA in your cells is a polymer. By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for “many parts.”. Each of those parts is scientists call a monomer (which in Greek means “one part”).
