摘要： A polymeric structure for use in the preparation of an organic optical component which polymeric structure comprises (a) a first layer (2) of an optically transmissive first polymer having a first refractive index, the first layer having a surface in which is defined at least one retaining feature (3); (b) an optically transmissive second polymer retained within the at least one retaining feature, the second polymer having a second refractive index which is greater than the first refractive index; and (c) an overlay of the second polymer having a maximum thickness of less than 1.5 mu m over the surface of the first layer. An organic optical component prepared from such a structure shows an optical loss of less than 2.0 dB.cm-1 at at least one wavelength in the range 300 to 1600 nm. The method of forming such a structure, e.g. waveguide, requires forming a line of contact between a flexible dispensing layer and the polymer surface in which the features defining the waveguide are located and progressively contacting the surface with the flexible dispensing layer such the line of contact advances across the surface. Sufficient of a resin (6) capable of forming the second polymer is applied along the line of contact and sufficient pressure is applied such that substantially all of the resin which is surplus to that required to fill the feature progresses with the line of contact.

摘要： Chlorine is scrubbed from a chlorine-containing gas using an aqueous feed liquor containing an excess of alkali to give an effluent liquor containing chloride and hypochlorite ions. The effluent liquor is recycled as part or all of the aqueous feed liquor. For at least part of the time, at least part of the effluent liquor is passed through a fixed bed of a catalyst for the decomposition of hypochlorite ions whereby hypochlorite ions are decomposed to oxygen gas and chloride ions. The resultant catalyst-treated liquor is mixed with the remainder, if any, of the effluent liquor and recycled, optionally together with added fresh alkali solution, as the aqueous feed liquor. Part of the effluent liquor is optionally discharged as a purge stream before or after passage through catalyst bed. The process may be operated in a continuous mode or in a semi-continuous mode wherein a reservoir holding the liquor to be recycled is periodically discharged, preferably through the catalyst bed, and then recharged with fresh alkali solution. Altternatively two reservoirs may be employed with one supplying the aqueous feed liquor while the other is being discharged and replenished. In the latter case, the reservoir being discharged may have its liquor discharged through the catalyst bed.
