Title Polyoxyalkylene Ammonium Salts and Their Use as Antistatic Agents 

Patent Application Material Patentability Anticipated Issuing Date  

Preparation of biodegradable salts derived from the reaction product of polypropylene ether amines and bis(perfluorobutylsulfonyl)-imine for use as antistatic agents. 

Observations In fabric applications there exists a need for fluorinated antistatic agents that 

A reactor was charged with 96% active bis(perfluorobutylsulfonyl)imine (1.26 mol) dissolved in water (760 g) and then treated with Jeffamine XJT-500 (0.66 mol) at 70°C over 30 minutes. The mixture was stirred an additional 15 minutes and the pH adjusted to 7-8. The solution was then concentrated under reduced pressure and 1042 grams of product isolated as an amber honey-like liquid.

Another factor to be considered is the time required to fabricate additional liners if the initial supply is depleted. Recently, General Atomics claimed it was able to fabricate 20-mil thick liners of the required diameter for the reactor. General Atomics plans to float a precious-metal liner in a cylindrical Hastelloy pressure vessel and use cooled elastomeric O-rings that have performed satisfactorily on other SCWO systems to form the SCWO reactor. The annular space between the liner and the vessel wall will be monitored for leaks to indicate when change-out of the liner is required. No decision has been made yet on whether to use platinum or Pt-20%Ir. Because they have markedly different mechanical properties, these two liner materials may require significantly different fabrication methods. Platinum is relatively weak and very ductile Pt-20%Ir is less ductile but 10 times stronger. Final selection of the liner material for use at the NECDF was scheduled for early 2000. Fabrication... 

If one deducts the approximately 1 million unregistered emigrants from the 5.3 to 6 million victims that Benz claims he found, this leaves him with 4.3 to 5 million victims. From this, one must further deduct the difference between the Soviet Jews who appeared in Soviet statistics and the real number (some 1.5 million), the number of Jews who died in the Soviet Union from other causes (deportation, war, partisan warfare, at least 500,000), the number of statistically fabricated additional Polish Jews (some 700,000) as well as the number of Hungarian Jews who probably did not succumb in their entirety (300,000), in other words, a total of roughly 4 million. This would leave Benz with a remainder of at most 1.3 to 2 million unsolved cases. 

A Branson ultrasonic horn was positioned over the fiber just before exit from the resin bath. The horn excited the fiber and resin, causing rapid agitation to occur. This movement accelerated the wetting of the fiber with the resin and expelled extraneous gaseous voids, allowing a void-free composite to be fabricated. Additional uniformity was achieved by rotation of the wound assembly during cure. The resin system used was a room-temperature-curing epoxy resin with a formulation of... 

This book presents the proceedings of the NATO Advanced Study Institute on Recent Advances in Polymeric Dispersions held in Elizonda, Spain, 23rd June - 5th July 1996. The book is composed of 35 papers contributed by a variety of international scientists with great experience in this area of work. The papers cover topics relating to polymeric dispersions and their apphcations such as synthetic rubber, paints, adhesives, binders for non-woven fabrics, additives in paper and textiles, leather treatment, impact modifiers for plastic matrices, additives for construction materials, pharmaceuticals, flocculants and rheological modifiers. The book covers fundamentals, discusses developments and unsolved problems and speculates on future research. Each chapter is well referenced. 

The woven textile substrate consisted of three pieces of cotton/polyester fabric (5 cm X 5 cm), which were cut from the main fabric. Additionally, two pieces of a hot melt adhesive interlining with the same dimensions as the fabric were used to laminate the three fabric layers together. Before laminating with the interlining, three yam electrodes from the same type of yam, approximately 6 cm in length, were sewn into the surface fabric. The yam electrodes were sewn close to each other in a center region of the device as illustrated in Fig. 20.1. 

Because the vine-twining polymerization based on the enzymatic polymerization provides amylosic supramolecular nanocomposites with well-defined stractures, which are hardly produced by conventional chemical synthetic method, the present approach will be extended to the systems using newly designed guest polymer components with hierarchically ordered stracture. Accordingly, the approach has a potential to fabricate additional eco-friendly supramolecular nanocomposites. Furthermore, the eco-liiendly supramolecular nanocomposites based on amylose are practically applicable to the biomedical and environmentally benign materials in the future.

Fibres and fabrics, among the most difficult materials to handle via transmission spectroscopy, are quite amenable to being studied via IRS. Multiple-bounce ATR-FTIR is of importance in identifying fibres, showing quantitative blend ratios, and in the analysis of fabric additives. ATR-FTIR was used to characterise the surface of graphitised carbon fibres [186]. 

Some valuable products with applications in paper coating, leather treatment, binders for nonwoven fabrics, additives for paper, textiles and construction materials, impact modifiers for plastic matrices, and diagnostic tests and drug delivery systems, can only be produced by emulsion polymerization. In addition, when needed (for example, for rubber for tires) latexes are easy to process into dry polymer. The main disadvantage of emulsion polymerization is that the product contains emulsifier and residues of initiator, which give it water sensitivity.
