    摘要: This invention relates to a process to increase the amount of polymer solute in a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to increase the amount of polymer solute in the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present. This invention also relates to a process to reduce the viscosity of a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to reduce the viscosity of the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present.

    摘要: An illuminable sign (1) including a plate (2) of a light-transmitting material, at least one three-dimensional body, such as a convex strip (7), also of a light-transmitting material, in the form of a symbol, lettering, decoration or the like, and positioned on or over a surface of the plate (2), and a light source (4). The light source (4) is positioned along at least part of an edge (3) of the plate (2), such that, when the light source (4) is switched on, light from the source (4) is coupled into the plate (2). The illuminable sign (1) closely resembles a neon sign.
