Investigation of the surface structure of polymers by chromatographic methods. V: Use of gel permeation chromatography in the study of the porous structure of copolymers of glycidyl methacrylate

摘要: Abstract Gel permeation chromatography (GPC) was used in an inversion function to characterize the porous structure of macroporous copolymers. Using glycidyl methacrylate copolymers as example, relationships between exclusion limit GPC and pore size porosity sorbent, distribution coefficient geometry size, peak widening morphology were established. Characteristic quantities are compared with results provided by other methods, especially electron microscopy, mercury porosimetry nitrogen sorption. It demonstrated that structures strongly cross-linked swollen dry states differ.
