Abstract: Commercial samples of high density, linear low density, and low density polyethylene were modified by injection of low concentrations of free radical initiator during extrusion. Molecular properties monitored included molecular weight distribution, degree of unsaturation, and branching. When the polyethylene feed to this reactive extrusion process had similar values of M,, but varying polydispersity, degree of branching and degree of unsaturation, the magnitude of the change in molecular weight distribution w…
