发明名称 Stabilized UV transparent acrylic composition
摘要 This invention relates to a UV stabilized transparent acrylic composition. More specifically the acrylic composition is stabilized with a carboxylic acid compound, which prevents or delays deterioration of the acrylic composition from high intensity UV radiation. The carboxylic acid compound is preferably an alpha hydroxylcarboxylic acid compound. The delay or prevention of deterioration results in the transmission of more UV radiation through the acrylic composition for longer periods of time. The composition is especially useful for tanning and other applications requiring transmission of high levels of UV radiation and resistance to discoloration. It is also useful in optical cable, LCD displays, acrylic storage media, and in HID devices.
