Periodic Water Table With James McDonald

The building blocks of polymers. What is a monomer? What are the various forms of monomers used in industrial water treatment? What functionality can each of these monomers bring? Are there synergies between them? How are monomers used to make polymers? When monomers are combined to form polymers, do all the polymers in a batch have the exact same discrete composition of monomers, or is the batch of polymer described more as an average of what the molecules are estimated to be when examined together? How can supply-chain shortages of a monomer impact industrial water treatment?
