Description
Изобретение относитс к переработке тер мопластов, Б частности по иметилт етакрипата , примен емого в оптике, 1свантовой электронике и в фотохимии Б качестве матрвд дл органических светофильтров, лааерньк устройств н фотохромных сред. Известен способ обработки изделий из подиметидалетакрипата, включающий выдержку в растворе уксусной киспоты при 8О°С в течение 70 час 1 . Однако этим способом невозможно получить издели прозрачные в ультрафиолетовой области спек тра. Цепь изобретени - придать иадели ам из полиметилметакрилата прозрачность в ультра фиолетовой области спектра. Это достигаетс тем что издели из по- лиметилметакрилата вьщерживают в 90 98%-ной уксусной кислоте 20-24 -lac. Пример. Пленки из пол метилметакрилата толщиной 0,1«1 мм помещают в тссусную кислоту на 24 час, затем тщательно промывают в дистиллированной воде и сушат в сушилке 2 час при . Аналогичгзым ибразом обредатывают изде ПИЯ в уксусной кислоте ЭСХ- н 94%..ной концен1рапии . Затем определ ют коэффисиент- сиектрального пропускани на спектрофотометре . Результаты испытаний приведены в таблице. Предлагаемый способ позвол ет получить издели , прозрачные в ульграфио;.гетовой области спектра длиной волны 240 нм, что сущее гвенно повышает их ценность дл использовани в качестве матриц, дл лазеров органических светофильтров и фотохромных сред.The invention relates to the processing of thermoplastics, B particularly for methylmetacate used in optics, 1swelto electronics and B photochemistry as matrvd for organic light filters, laernck devices and photochromic media. There is a method of processing products from podimetidalekripata, including exposure to the solution of acetic acid at 8 ° C for 70 hours 1. However, using this method it is impossible to obtain transparent products in the ultraviolet region of the spectrum. The chain of the invention is to impart transparency to polymethyl methacrylate in the ultraviolet region of the spectrum. This is achieved by the fact that polymethyl methacrylate products are contained in 90–98% acetic acid 20–24 -lac. Example. Films of methyl methacrylate with a thickness of 0.1 "1 mm are placed in citric acid for 24 hours, then thoroughly washed in distilled water and dried in a dryer for 2 hours at. Similarly, products of PIA in acetic acid, ESCH-94%, are concentrated. The coefficient of spectral transmission is then determined on a spectrophotometer. The test results are shown in the table. The proposed method makes it possible to obtain products that are transparent in ulgrafio; the hethe region of the wavelength of 240 nm, which existently increases their value for use as matrices for lasers of organic light filters and photochromic media.
