Provided are a phase change developer for liquid electrophotography and a method for electrophotographic imaging using the same. The phase change developer includes (a) a carrier having a Kauri-butanol number less than 30and (b) an organosol comprising a graft (co)polymeric steric stabilizer covalently bonded to a thermoplastic (co)polymeric core that is insoluble in the carrier, and the (co)polymeric steric stabilizer comprises a crystallizing polymeric moiety that independently and reversibly crystallizes at or above 30°C, wherein the phase change developer has a melting point at or above 22°C.

Processes for dyeing hydrophobic textile fibers with a colorant using a supercritical carbon dioxide dyebath are described. One employs cooling without venting or removing carbon dioxide to a target temperature at or below the glass transition temperature of the fiber, followed by venting. The other process employs venting, without cooling, to a target carbon dioxide density, where the dye is no longer soluble, then cooling, then venting. The figure is a detailed schematic of a system suitable for use in the dyeing process. In the figure, dyeing system (10) comprises filling and pressurization subsystem (A), dyeing subsystem (B), and venting subsystem (C). Carbon dioxide is introduced into filling and pressurization system (A) via supply cylinder (12) through line section (14) and regulating valve (16) and is cooled in condenser (26) supplied by chiller (28). As the carbon dioxide leaves mixer (38) it is heated at (40) and enters dyeing subsystem (B) through valve (66) and/or valve (64). During venting carbon dioxide flows from dyeing subsystem (B) through control valve (154) and into separator vessel (156) of venting subsystem (C).
摘要:
A method and apparatus for assessing tissue for the presence of oedema and, in particular, lymphoedema is disclosed. The method is based on measurement of bioelectrical impedance at a single low frequency voltage. Measurements are taken of two anatomical regions of a subject and analysed to give an indication of tissue oedema.
摘要:
A melt-processable thermoplastic composition is described, which comprises a) 50 - 99.5 wt.% of a melt-processable thermoplastic polymer and b) 0.5 - 50 wt.% of a particulate polymer comprising the residues of a monomer mixture comprising 50 - 100 wt.% of MMA, at least 0 - 50 % of an ethylenically unsaturated comonomer comprising at least one alkyl acrylate or methacrylate and 0 - 10 wt.% of a copolymerisable cross-linking monomer said particles having a maximum dimension of 5 mm. The compositions have reduced surface gloss and may be useful for forming building components or in any other application in which a low gloss surface is required. A method of making the composition and its uses, for example its use as a capstock material, are also described.
摘要:
The present invention provides a composition comprising: i) at least one compound of formula (I), wherein R1 and R2 are independently selected from a group consisting of hydrogen, unsubstituted or substituted C1-19hydrocarbyl or a group of formula (II), wherein Q is a bond or an unsubstituted or substituted hydrocarbyl group; wherein R3 is selected from a group consisting of hydrogen and unsubstituted or substituted C1-18hydrocarbyl; wherein the R1-C-R2 backbone is from 5 to 20 atoms in length; wherein each A and B is independently an unsubstituted or substituted unsaturated cyclic hydrocarbyl group; and wherein n is an integer from 0 to 10; and ii) a diluent or carrier; wherein the compound(s) of formula (I) is present in an amount sufficient to provide, at 30 °C, at least 1 wt % of iron, based on the weight of the composition.
