The solution behavior of metal maleate low density polyethylene graft ionomers (LDPE-g-MAMe) in extremely dilute and dilute solutions was investigated in this study. The concentration region was divided into three parts because of the different viscosity-concentration relations of these ionomers. The eta (sp)/C-C relations of zinc maleate low density polyethylene graft ionomers (LDPE-g-MAZn) were studied in detail and compared with those of low-density polyethylene and low-density polyethylene-g-maleic anhydride. Finally, the viscosity-concentration relations of LDPE-g-MAMe (Na, K, La) were also studied and compared with one another.
