Reactive melt extrusion grafting of thermoplastic polyvinyl alcohol/polyolefin blends
A method for preparing a compatible blend of polyolefin and thermoplastic polyvinyl alcohol comprising: (a) melting polyolefin in the initial elements of a melt extruder, (b) adding and melt blending an unsaturated carboxylic acid or anhydride with the melted polyolefin downstream in the extruder, (...

| description | A method for preparing a compatible blend of polyolefin and thermoplastic polyvinyl alcohol comprising: (a) melting polyolefin in the initial elements of a melt extruder, (b) adding and melt blending an unsaturated carboxylic acid or anhydride with the melted polyolefin downstream in the extruder, (c) adding peroxide to the melt blend and grafting the unsaturated carboxylic acid or anhydride onto the polyolefin, and (d) melt blending thermoplastic PVOH into the grafted polyolefin/unsaturated carboxylic acid or anhydride melt mixture. |
