Abstract: Disclosed is a polyethylene composition. The composition comprises single-site multimodal resin A and single-site multimodal resin B, wherein resin A differs from resin B in molecular weight, in monomeric composition, in density, in long chain branch concentration or distribution, or in combinations thereof. Disclosed is also a method for making the polyethylene composition. The method comprises polymerizing, in the presence of two or more single-site catalysts, ethylene or its mixture with a C3-C10 ?-olefin to form a first multimodal resin and continuing the polymerization in the presence of the same catalysts but in a different hydrogen concentration, in a different monomer composition, or at a different temperature to form a second multimodal resin.

Abstract: Methods for making polyolefins are disclosed. One method comprises polymerizing an olefin in the presence of a catalyst system comprising a single-site complex, an agglomerated metal oxide/clay support-activator, and an ionic borate. Including an ionic borate with the support-activator provides an unexpected boost in catalyst activity and gives polyolefins with high molecular weight and improved comonomer incorporation. In another method of the invention, an olefin is polymerized in the presence of an indenoindolyl metal alkylated complex and an agglomerated metal oxide/clay support-activator. Use of alkylated indenoindolyl complexes with the support-activators provides improved activity compared with metal halides.

Abstract: Ethylene polymer composites, concentrates and a process utilized for their preparation are provided. The composites of the invention have increased melt strength compared to the base resin and other improved physical characteristics. The composites contain an organically modified clay and may also contain a compatibilizng agent, depending on the base resin used.

Abstract: A virtual well plate system includes a base including a base plate having an upper surface with a hydrophobic region which defines hydrophilic domains, each hydrophilic domain adapted to hold a droplet of liquid therein; a movable lid including a lid plate having a lower surface with a hydrophobic region which defines hydrophilic domains, each hydrophilic domain adapted to hold a liquid droplet in a hanging manner; and a resistance arrangement mounted to the base and/or lid and which maintains the base and lid in an assembled condition such that the base plate and lid plate are maintained at a sufficient distance to prevent formation of virtual wells by the droplets, and which permits movement of the lid toward the base upon application of an external force sufficient to overcome a resistance of the resistance arrangement, to form virtual wells by combining the droplets.

Abstract: A self-contained portable apparatus for cleaning a floor cover, such as a carpet. The apparatus comprises vacuum chambers; electric motor driven vacuum creating mechanisms; vacuum nozzles operatively associated with the vacuum chambers; a spray bar and nozzles operatively connected with a source of water; a source of emulsifying agent; a siphon device for extracting emulsifying agent from its source and introducing it into the water flowing to the spray nozzles; a heating element for heating the water as it flows to the spray bar; and appropriate valving and plumbing; all of which are included within a single housing. In addition, the housing includes a roller so that the apparatus may be easily rolled over the floor cover to be cleaned. There is also included a hand tool operatively connected with one of the vacuum chambers of the apparatus for cleaning the floor in hard to get at places too small or inconvenient to reach with the self-contained floor cover cleaning apparatus.
