Polyethylene mer structure
WebPoly means “many” and mer means “units”. Polymeric structures are either long chains of repeating molecules (called macromolecules) or large networks of repeating molecules. Usually the chain or network has a carbon backbone with hydrogen and other elements arranged on it such as O, N, F, Si, S. Hence most polymers are organic materials.
