ABSTRACT:
A compositional blend having from about 1 weight percent to about 85 weight percent of a modified polyolefin and from about 99 weight percent to about 15 weight percent of modified poly(ethylene oxide). The modified polyolefin and modified poly(ethylene oxide) have a total of from about 1 weight percent to about 30 weight percent of a monomer grafted thereto. Included is a method for making the blend comprising using a single pass extruder to perform the steps of melt blending the polyolefin, poly(ethylene oxide), the monomer and a sufficient amount free radical initiator to graft from about 1 percent to 100 percent of the monomer onto the polyolefin and poly(ethylene oxide).
