IMPROVEMENTS IN FLUORESCENT MATERIALS

摘要

A fluorescent dyed polymer composition useful in a luminescent sunlight collector is prepared by a process including dissolving by means of ultrasonic agitation a fluorescent dye in a solution of mono(methyl methacrylate) or partially polymerised methyl methacrylate. A sufficient quantity of organic peroxide initiator is added to the solution either before, during or after the dissolution of the fluorescent dye in the solution so that, at sufficient temperature, polymerisation is initiated so as to produce a fluorescent dyed polymer composition without the formation of voids or bubbles. When suitably cast, the fluorescent dyed polymer composition may take the form of a luminescent sunlight collector.
