Abstract
Substantially solid state thermoplastic thermal radiation suppressor composition for suppressing thermal radiation transmission comprise a thermoplastic substance (e.g., a polymer of polymerized styrene, methyl methacrylate and 2-isopropenyl-2-oxazoline) in intimate contact with a composition (e.g., a polymer of polymerized ethylene and acrylic acid) which exhibits a refractive index essentially equal to that of said thermoplastic substance at one temperature but a refractive index different from that of said thermoplastic substance at another temperature. The thermal radiation suppressor compositions exhibit good physical properties and can be employed in the form of thermoplastic sheets or films. The compositions are useful as devices in greenhouses, skylights, etc.
