摘要:
AbstractThe molecular weight distributions of three polydimethylsiloxanes (PDMS) have been determined by gel‐permeation chromatography (GPC), by gas–liquid chromatography (GLC), and by precipitation fractionation. The GPC data are greatly improved by correction for band spreading. For a high molecular weight polymer the corrected distribution agrees closely with the theoretical molecular weight distribution calculated from polymerization kinet
