    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.

    摘要: In a process for producing a polymer blend, at least one first monomer is polymerized in a first slurry phase reaction zone in the presence of a supported first catalyst to produce a thermoplastic first polymer having a crystallinity of at least 30%. At least part of said first polymer is then contacted with at least one second monomer different from said first monomer in a second solution phase reaction zone in the presence of a second catalyst and in the absence of polyenes under conditions to produce a second polymer having a crystallinity of less than 20%.
