摘要:
Embodiments of the invention provide systems and methods for remote sensing and/or monitoring utilizing a sensing device, such as may be implemented in a patch that can be placed on or affixed to a subject, where the sensing device includes multiple sensors. For example, one embodiment of the present invention includes a wireless human temperature skin patch providing accurate measurement of human temperature from a sensing device applied to the skin and even in the presence of differing ambient temperature. In such an embodiment, the patch can include, for example, a flexible, breathable bandage or adhesive strip or pad to affix the sensing device to a patient. The sensing device can include multiple sensors such as two or more temperature sensors that can be used to accurately determine the patient's core body temperature from the measured temperature at the skin.

A process for preparing a starch-based thermoplastic hydroxy-functional polyether comprising (1) feeding from about 40 to about 98 weight percent starch and from about 2 to about 60 weight percent of a thermoplastic hydroxy-functional polyether derived from monomers containing one or more epoxy groups into a processing equipment at a temperature and for a time sufficient to provide a compounded mixture of the components and then (2) forming the compounded mixture into pellets. The pellets are suitable for injection molding and other thermal processes.

A process for producing a branched polymer from a vinyl aromatic monomer comprising: A) contacting a vinyl aromatic monomer with a difunctional anionic initiator under conditions such that a dianion macromer is formed, B) contacting the dianion macromer with a multifunctional coupling agent having at least 3 reactive sites under polymerization conditions such that branches form during polymerization, and C) contacting the product of step B with a terminating agent under conditions such that the reactive sites are terminated.
摘要:
In one embodiment, the present invention is a polymeric composition, in pellet form, which comprises a vinyldene chloride interpolymer, and a friction reducing polymer (FRP) in an amount of from about 0.1 to about 40 weight percent, said weight percent being based on the total weight of the polymeric composition. The FRP is selected to selected to lower the frictional coefficient and the mechanical energy to extrude of the polymeric composition. In another embodiment, the present invention is a polymeric composition, in either power or pellet form, possessing improved extrudability, composition comprises a vinylidene chloride interpolymer in an amount of from about 55 to about 99.85 weight percent, a FRP in an amount from about 0.1 to about 40 weight percent, and a salt of an acid in an amount of between about 0.05 and about 5 weight percent, said weight percents being based on the total weight of the polymeric composition.
