Polyamines having at least two amine groups are incorporated into a polymer system comprising an anionic surfactant and a polymer having at least one anionic pendant group. The resulting polymer system typically exhibits at least one improved physical property.

Articles, in particular non-pressure mono- or multi-layer pipes, prepared by extrusion, molding and combination thereof, comprising a heterophasic polyolefin composition comprising (1) 65-95% of a crystalline propylene polymer insoluble in xylene at ambient temperature in an amount over 85% and having a polydispersity index ranging from 4 to 13 and an intrinsic viscosity value ([.eta.].sub.1) of over 2.2 dl/g, and (2) 5-35% of an elastomeric olefin polymer of ethylene with a C.sub.3-C.sub.10 .al...

The invention provides an article comprising a first layer comprising a first substantially solid partially-fluorinated thermoplastic polymer, and a second layer comprising a second substantially solid partially-fluorinated thermoplastic polymer, the second layer bonded to the first layer, wherein the first polymer and the second polymer have different compositions. The invention also provides layered articles and processes for preparing layered articles.

The invention provides protective articles comprising a backing that comprises a fluorinated polymer and a curable adhesive on at least one layer of the backing. The protective articles of the invention may be used to provide substrates or articles of the invention having a fluorinated surface. The invention also provides methods of preparing such articles, methods of repairing appliques, and methods of edge sealing appliques.

This invention provides security articles comprising fibers, threads and fiber sections ("dots") possessing multiple verification characteristics. The fibers possess unique and difficulty duplicated combinations of complex cross-sections, components, and multiple luminescent responses. The many verifiable characteristics of the security fibers, threads and dots provide high levels of protection against fraudulent duplication of articles in which they are incorporated. The manifold security featu...

Nanofibrous articles can be manufactured by a process that includes preparation of a surface of a substrate to provide an adhesion mechanism for securing the nanofibers to the surface. The nanofibers can be dispersed in an area near the substrate for the purpose of being adhered to the surface. If an ordered arrangement of nanofibers is required, an electric field can be provided in the area where the nanofibers are dispersed to selectively control an ordering of the nanofibers as they are adher...

A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles, e.g. refractory oxide, carbide or graphite, and a carbon-rich binder, e.g. tar, pitch or an organic (preferably aromatic) polymer that degrades to form carbon on pyrolysis, and then firing the porous article to generate the carbon matrix in which the...

The present invention provides an improved disposable article for the absorption and containment of urine or other body exudates, for example a diaper, training pants or an adult incontinence article, that has a high fecal fluid intake rate as measured by the Fecal Fluid Intake Test.

Laundry articles comprise a water-insoluble substrate and a particulate soil absorber comprising a crosslinked polyamide including units having a nucleophilic group. The particulate soil absorber is adhered to the water-insoluble substrate and is effective for inhibiting transfer or redeposition of particulate soil to items in a wash solution. Methods for making such articles comprise adhering a particulate soil absorber comprising a crosslinked polyamide including units having a nucleophilic gr...
