Abstract: Ethylene copolymers having a relatively high melt flow ratio and a multimodal profile in a temperature rising elution fractionation (TREF) plot are disclosed. The copolymers can be made into film having good dart impact values and good stiffness properties under decreased extruder pressures.

Abstract: A polymer blend comprising first and second polyethylene copolymers is presented which has good processability, and which when made into film shows good toughness-stiffness balance, reasonable MD tear, as well as good optical properties.

Abstract: Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.

Abstract: Polyethylene films having a good balance of optical and mechanical properties are disclosed. The films are derived from ethylene copolymer compositions made with a suitably substituted phosphinimine catalyst. The ethylene copolymers have very narrow molecular weight distributions and broadened comonomer distributions.

Abstract: A method for altering the polymer architecture of ethylene copolymers made with a supported phosphinimine polymerization catalyst. The method involves changing the amount of a catalyst modifier added to a reactor separately from or together with a supported phosphinimine polymerization catalyst.

Abstract: Munc18 proteins facilitate formation of SNARE complexes known to mediate membrane fusion. Much is known about the fusion of secretory granule (SG) to plasma membrane, mediated by Munc18a-SNARE complexes. It has been found that another Munc18 isoform, Munc18b, mediates SG-SG fusion which causes potentiation of secretion. The present invention has identified specific site mutations within Munc18b which further increased (called KR mutant) or reduced (called E59K mutant) SG-SG fusion compared to wild type (WT) Munc18b, causing amplification or reduction of insulin secretion, respectively. Compounds identified that mimic the actions of Munc18b-WT and Munc18b-KR mutant which increase SG-SG fusion, and those which mimic Munc18b-E59K mutant that block SG-SG fusion, are useful for treating and/or preventing diseases and/or conditions, whose underlying bases are a deficiency or excess of SG-SG fusion, respectively.

Abstract: The invention concerns processes and solutions for the treatment of copper alloy surfaces, which are subsequently to be firmly bonded to polymeric material. The solution is used, in particular for firmly bonding lead frames to encapsulating molding compounds (polymeric material). The solution contains an oxidant, at least one acid, at least one adhesion-enhancing compound characterized in that the solution additionally contains fluoride ions in an amount of at least 100 mg per litre and chloride ions in an amount of 5 to 40 mg per litre. The solution is particularly useful for treatment of copper alloy surfaces, containing alloying elements selected from the group consisting of Si, Ni, Fe, Zr, P, Sn and Zn.

Abstract: A blend of ethylene homopolymers contains at least one blend component having a very low molecular weight and a narrow molecular weight distribution. The blend has surprisingly high density and low hexane extractables. The blend is suitable for the manufacture of a wide variety of plastic goods including extruded goods and molded goods. Plastic film prepared from the blends of this invention have a low Water Vapor Transmission Rate (“WVTR”).

Abstract: Multilayer “barrier” films which have excellent Water Vapor Transmission Rate (WVTR) performance are prepared using a core layer which comprises a blend of two different high density polyethylenes (HDPEs) and a nucleating agent. The films are suitable for the preparation of packages for dry foods such as crackers and breakfast cereals.
