A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage.

Автор: Alejandra Lopez-Santiago, Palash Gangopadhyay, Robert A. Norwood
Принадлежит: Arizona Board of Regents of University of Arizona

Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

Graft compositions, useful for tie-layer adhesives, are disclosed. The graft compositions comprise the reaction product of a live, grafted polyolefin and an olefin elastomer. The grafted polyolefin is first made by heating a polyolefin and an unsaturated monomer. Further reaction of the live, grafted polyolefin with an olefin elastomer provides the graft composition. Grafting efficiency is boosted dramatically by the presence of the olefin elastomer and use of the additional reaction step. The graft composition, when formulated into a tie-layer adhesive at low concentration, affords multilayer structures with good adhesion and high clarity.

Viscosity control in compositions comprising plant fiber materials

Номер: US20120142909A1
Автор: Brock Lundberg
Принадлежит: Fiberstar Bio Ingredient Technologies Inc

Pectinases, such as Pectinex™ Ultra SP-L (composed of the enzyme Polygatacturonase, a type of pectinase which is derived from Aspergillus aculeatus ) or pectinmethylesterases were used to decrease or increase, respectively, the viscosity of fiber solutions, especially solutions with highly refined cellulosic thickeners, and particularly those made of highly refined cellulosic parenchyma cell wall fiber solutions. The enzyme can reduce the viscosity up to 95% or increase the viscosity 100 fold. At lower concentrations the enzyme requires up to a few days of reacting to reach the full reduction in viscosity. Pectinex™ Ultra SP-L has an optimum pH of 4.5-5 and a temperature optimum of 40° C. By controlling the viscosity available from the dried, treated highly refined cellulosic fiber compositions, tailored powder compositions can be provided that will provide precise viscosities when rehydrated in solutions at a constant concentration.

A method of separating a poly(arylene ether) from a solvent includes treating a poly(arylene ether)-containing solution with a devolatilizing extruder to form an extruded composition, and cooling the extruded composition with a cooling device that does not immerse the extruded composition in water. The composition may be used to isolate a poly(arylene ether) from the solvent-containing reaction mixture in which it is prepared, or to remove solvent from a multi-component poly(arylene ether)-containing thermoplastic composition.
