Scientific definition of polymer
Web28 Aug 2024 · Molecular weight analysis of polymers Gel permeation chromatography (GPC) Gel permeation chromatography is also called size exclusion chromatography. It is widely used method to determine high molecular weight distribution. In this technique, substances separate according to their molecule size. WebA commonly used definition of polymer is a material that is composed of many monomers (from 10s to 1000s) all linked together to form chains. A monomer can be composed of one to many atoms which form the base unit which is repeated to form a polymer, as represented in the figure below. Poly means many; mer means to repeat.
