Abstract: Decreasing the transmittal of near infra-red radiation through transparent glassy polymers, such as methacrylic ester polymers or those containing a high proportion of N-methyl dimethylglutarimide units, by use of a blended absorber is extremely difficult to accomplish because of the thermal instability of such absorbers under conditions necessary to process the glassy polymer. Use of very low levels of a specific class of thermally stable additives produces a thermally stable polymer blend which may be converted into transparent sheet exhibiting lowered transmittal of near infra-red radiation and useful for many glazing applications.

Abstract: Disclosed are novel anthraquinone compounds containing tetra-p-phenylenediamine substituents, particularly useful in molding type polyester compositions and possessing strong infrared absorptivity. This property renders these compounds attractive as additives for increasing the infrared energy absorptivity of polyesters either from high intensity quartz lamps or from certain laser systems. These compounds are particularly useful in bottle polyester material for increasing the blow-mold parison reheat rate, and in the printing of plastic articles with lasers.
