摘要： 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.
摘要翻译：通过使用混合的吸收剂，通过透明玻璃状聚合物（例如甲基丙烯酸酯聚合物或含有高比例的N-甲基二甲基戊二酰亚胺单元的那些）来降低近红外辐射的传递是非常困难的，因为这种热不稳定性在处理玻璃状聚合物所需的条件下进行吸收。使用非常低水平的特定类别的热稳定添加剂产生热稳定的聚合物共混物，其可以转化为透明片材，其表现出近红外辐射的低透射率，并且可用于许多玻璃应用。
