    摘要： An edge lit illumination device is described. The device has at least one light source (13, 14) and a light transmission member (10) having at least one light output surface (12) and at lest one light ingress edge substantially perpendicular to the surface. The light source (13, 14) is located adjacent to the light ingress edge so that light from the light source (13, 14) enters the transmission element (10) via the ingress edge and propagates through the member. At least one light output surface (12) is uniformly roughened across its surface. The surface (11) of the said member opposite the output surface (12) has a pattern of light diffusing elements thereon. A method of producing a light transmission member for an illumination device is also described.

    摘要： An edge-lit illumination system comprising a light transmitting sheet (10) which has a surface treatment, capable of reflecting or scattering light, on at least one of its opposing surfaces (11, 12), a light source (13) positioned in proximity to, and adjacent to, an edge of this sheet, and a reflective surface (14) positioned adjacent to an edge of the sheet, at an obtuse angle (18) to the plane of the sheet and extending away from one surface of the sheet. The reflective surface is preferably disposed adjacent to the edge of the light transmitting sheet having the light source adjacent to it. The obtuse angle preferably ranges from 100 to 145 degrees. This invention gives an increase in the area of illumination across the light transmitting sheet.

    摘要： An acrylic polymeric composition comprising a melt blend of a thermoplastic high molecular weight acrylic material (HMWA) and a thermoplastic low molecular weight acrylic material (LMWA) is described. At least 70% w/w of the HMWA and the LMWA comprises an alkyl (alk) acrylate (co)polymer. The HMWA has a weight average molecular weight (Mw) of between 40k Daltons and 1000k Daltons and the LMWA has a weight average molecular weight (Mw) of between the entanglement molecular weight (Me) (expressed in k Daltons) and 250k Daltons. A method of producing an acrylic polymeric composition and the use of an acrylic polymeric composition are described together with thick section moulded products.

    摘要： The present invention provides a moisture-reactive hot melt adhesive composition. The composition comprises: (a) urethane prepolymer, derived from at least one polyol and at least one polyisocyanate, and having free isocyanate groups effective to cure the composition in the presence of moisture; and (b) acrylic(co)polymer, wherein the acrylic (co)polymer comprises one or more residues of an (alk)acrylate (co)monomer of formula (I) wherein the group R contains at least one cyclic, tertiary or quaternary carbon, R is attached to the group —C(O)O— via a cyclic or tertiary carbon atom and wherein R′ is a hydrogen or an alkyl group. The invention extends to use of an acrylic (co)polymer in a moisture reactive hot melt adhesive composition as a stringing reducing agent; a substrate comprising the moisture reactive hot melt adhesive composition; and a method of bonding materials together with the composition.
