Characterization of ionomer solutions. I. Division of the concentration region and viscosity-concentration functions

The solution behavior of metal maleate low density polyethylene graft ionom ers (LDPE-g-MAMe) in extremely dilute and dilute solutions was investigated in this study. The concentration region was divided into three parts becau se of the different viscosity-concentration relations of these ionomers. Th e eta (sp)/C-C relations of zinc maleate low density polyethylene graft ion omers (LDPE-g-MAZn) were studied in detail and compared with those of low-d ensity polyethylene and low-density polyethylene-g-maleic anhydride. Finall y, the viscosity-concentration relations of LDPE-g-MAMe (Na, K, La) were al so studied and compared with one another. (C) 2001 John Wiley & Sons, Inc.
