Polymers experiment

WebExperiment 16: Polymers Products that are commonly referred to as “plastics” by the general public are known to chemists as polymers. A polymer is a macromolecule which consists of small molecular units that are repeated over and over again to form a long chain. The small molecular unit is called a monomer.

WebSep 12, 2024 · In this case, the relationship is described by the Mark-Houwink equation: (4.2.1) [ η] = K M α. In this equation, [η] is the intrinsic viscosity; that's the viscosity attributed to the solute, rather than the viscosity of the solvent itself. M is the molecular weight. K and α are constants for a particular polymer. WebThat’s right, superabsorbent polymers are used to lock moisture in baby diapers so that they don’t leak. The polymers we’ll be using in this experiment absorb water, too — a lot of water, in fact.
