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 a 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 a polyolefin, a poly(ethylene oxide), a 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).
Claims20
A composition of matter comprising a 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 a modified poly(ethylene oxide), wherein said modified polyolefin and said modified poly(ethylene oxide) have a total of from about 1 weight percent to about 30 weight percent, based on the total amount of polyolefin and poly(ethylene oxide), of a monomer selected from the group consisting of polyethylene glycol acrylates and polyethylene glycol methacrylates and derivatives thereof grafted onto said polyolefin and said poly(ethylene oxide).
A method for preparing a blend of a modified polyolefin and a modified poly(ethylene oxide) comprising melt blending an amount of polyolefin, an amount of a poly(ethylene oxide), an amount of a polyethylene glycol acrylate or polyethylene glycol methacrylate or a derivative thereof, and a sufficient amount free radical initiator to modify said polyolefin and said poly(ethylene oxide) by grafting from about 1 percent to 100 percent of said monomer onto said polyolefin and said poly(ethylene oxide).
