Gel Permeation Chromatography - A device used to determine the molecular weight distribution of a polymer.
GPC - An abbreviation for Gel Permeation Chromatography.

Degree of polymerization

Degree of polymerization - The average number of monomer units per polymer molecule, a measure of molecular weight. In most plastics, the molecular weight must reach several thousand to attain worthwhile physical properties.
