The science of polymer molecules
WebbA polymer's molecular weight is the sum of the atomic weights of the individual atoms that comprise a molecule. It indicates the average length of the bulk resin's polymer chains. … WebbA polymer is a substance made of many repeating units. The word polymer comes from two Greek words: poly, meaning many, and meros, meaning parts or units. A polymer can be thought of as a chain in which each link is the “ mer, ” or monomer (single unit). The chain is made by joining, or polymerizing, at least 1,000 links together.

Webb1 jan. 1970 · The formation of any polar organic molecule or repeating unit of a polymer in fact always involves replacement of a hydrogen atom by other elements forming the polar group. This brings about a change in volume and in molecular weight. Webb20 maj 2016 · Polymers rule our lives, quite literally. DNA is a polymer. The long gooey strands of mozzarella cheese that stretch as you take a slice of pizza are a polymer, too. In its simplest terms, a polymer is the bonding of many molecules into long, often-strong chains. If you could stretch it out, a single molecule of DNA would measure 2 meters end …
