Publication number: 20060004135Abstract: Composites of macrocyclic oligomers and a filler material are made in a masterbatch process. The masterbatch contains at least 15% by weight of the filler material. The filler material is preferably a submicron sized material and is especially a clay or other layered material that can become at least partially exfoliated. The masterbatch can be let down into more of the macrocyclic oligomer, another polymer, another polymerizable material and subjected to polymerization conditions to form a nanocomposite material. Alternatively, the masterbatch can be polymerized to a high or intermediate molecular weight, and then blended with additional oligomer, polymer or other polymerizable material.Type: ApplicationFiled: June 16, 2005Publication date: January 5, 2006Inventors: Michael Paquette, Robert Dion, Martin Beebe, Peter LeBaron, Mark Barger, Parvinder Walia

Publication number: 20030215655Abstract: Improved multi-layer coextruded blow-molded objects (such as fuel containers) having at least a barrier layer and a support layer are disclosed together with improved methods for preparing such objects. The barrier layer includes an amount of modified polyolefin having approximately the same density as the support layer, wherein the modified polyolefin is prepared by grafting an unsaturated carboxylic acid or a derivative thereof to the polyolefin, the modified polyolefin being added in an amount such that the gas-barrier layer sufficiently adheres to the adjacent layer and such that the gas barrier properties of the fabricated article are still adequate. The present invention also relates to modification of the rheology of base resins, such as PET (a preferred material for the barrier layer), so that they more closely match the rheology of high density polyethylene (a preferred material for the support layer).Type: ApplicationFiled: November 1, 2002Publication date: November 20, 2003Inventors: Mark A.

Patent number: 5446936Abstract: A cross-support member extends between the opposed side panels of an inverted U-shaped boot insert to prevent the side panels from collapsing toward one another. The cross-support member may be a separate structural element which is associated with the inverted U-shaped boot insert, or may be formed as an integral part of the inverted U-shaped boot insert (e.g., by partially cutting out the cross-support member from at least one of the side panels and/or by affixing the cross-support member to an interior surface of at least one of the side panels). The cross-support member may itself include lateral stiffening panels of desired geometry (e.g., triangular, rectangular, etc.) which are preferably formed as an integral part of the cross-support member by folding a lateral section of the cross-support member angularly out of the cross-support member's plane.Type: GrantFiled: April 1, 1994Date of Patent: September 5, 1995Inventor: Mark A.

Patent number: 5091250Abstract: A light-stable, optically clear laminate construction and method of making it which utilizes inexpensive styrenic polymers is provided. The laminate formed exhibits strong interfacial adhesion without the need for additional glue or adhesive layers through the use of pendant functionalized hydroxyl groups incorporated into the styrenic polymer by copolymerization. These pendant hydroxyl groups react with active pendant ester groups on the other polymer layer in the laminate to form strong covalent interfacial bonds by heating the layers, preferably either in a compression molding step or during coextrusion of the layers.Type: GrantFiled: February 6, 1990Date of Patent: February 25, 1992Assignee: The Dow Chemical CompanyInventors: Pak-Wing S.
