CATION-NEUTRALIZED IONOMERS AND FOAMS THEREOF

摘要

Provided are ionomer compositions neutralized with trivalent cations. The melt strength and melt viscosity are higher, and the sensitivity of melt viscosity to temperature is lower, compared to ionomer compositions that contain the same base resin and are neutralized with monovalent or divalent cations only. The compositions are suitable for preparing substantially open cell foams used in multilayer structures and articles such as diapers, adult incontinence pads and sanitary napkins.
