In one aspect the invention provides a melt process for preparing a functionalized olefin multiblock interpolymer, said process comprising grafting onto the backbone of the olefin multiblock interpolymer at least one compound comprising at least one 'amine-reactive' group to form a grafted olefin multiblock interpolymer, and reacting a primary-secondary diamine or an alkanolamine with the grafted olefin multiblock interpolymer, without the isolation of the grated olefin multiblock interpolymer.

Functionalized olefin polymers, compositions and articles prepared therefrom, and methods for making the same

The invention provides polyolefin blend compositions of polar and/or non-polar polymers, with at least one functionalized polyolefin polymer selected from the group consisting of: amine functionalized, hydroxyl functionalized, imide functionalized, anhydride functionalized, or carboxylic acid functionalized polyolefin polymers. The invention also provides methods for making the functionalized polyolefin polymer. The invention also provides for materials and articles containing at least one component prepared from such compositions.

Functionalized olefin polymers, compositions and articles prepared therefrom, and method of making the same

Compositions comprising a polyolefin polymer and an expanded graphite exhibit uniform conductivity over a broad range of temperature. In one embodiment, the polyolefin polymer is polypropylene or polyethylene homopolymer or a polypropylene or polyethylene copolymer. The compositions provide uniform conductivity and can be used as a conductive formulation for medium and high voltage cable components.

Semi-conducting polymer compositions for the preparation of wire and cable

A concrete article comprised of concrete having therein a reinforcing polymer that has a surface comprised of a thermoplastic hydroxy-functionalized polyether or polyester. The concrete article is made by mixing concrete, water and a reinforcing polymer that has a surface comprised of a thermoplastic hydroxy-functionalized polyether or polyester and curing said concrete mixture forming the concrete article.

Architectural concrete and process to make same

A process for preparing a starch-based thermoplastic hydroxy-functional polyether comprising (1) feeding from about 40 to about 98 weight percent starch and from about 2 to about 60 weight percent of a thermoplastic hydroxy-functional polyether derived from monomers containing one or more epoxy groups into a processing equipment at a temperature and for a time sufficient to provide a compounded mixture of the components and then (2) forming the compounded mixture into pellets. The pellets are suitable for injection molding and other thermal processes.
