Beschreibung
Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: invention relates to making articles with an elongated shape with a regular microrelief on the surface, which can be used as elements of optoelectronic devices and information display systems. In the first version, articles with an elongated shape made from glass-like non-oriented or partially oriented polymer are treated with low-temperature plasma. The articles are then heated to temperature higher than the glass transition point (Tg). The articles are stretched in at least one direction. The articles are cooled to temperature lower than Tg of the polymer while fixing the size of the article in the direction of stretching. In the second version, the non-oriented or partially oriented article made from amorphous glass-like or polycrystalline polymer is treated with low-temperature plasma. The article is stretched at temperature lower than Tg for the amorphous polymer and lower than melting point (Tm) for the polycrystalline polymer. In the third version, an article in high-elastic state of the polymer is treated with low-temperature plasma. The article is stretched while fixing the size of the stretched article in the direction of stretching. In the fourth version, an article made from amorphous or polycrystalline polymer is used. The article is stretched at temperature higher than Tg for the amorphous polymer and lower than Tm for the polycrystalline polymer. The article is treated with low-temperature plasma while fixing the size of the article with subsequent removal of the fixing. ^ EFFECT: easier formation of a regular microrelief on the surface of polymer articles. ^ 8 cl, 7 dwg, 4 ex Изобретение относится к области получения полимерных изделий вытянутой формы с регулярным микрорельефом на поверхности, которые могут быть использованы в качестве элементов оптоэлектронных приборов и систем отображения информации. В первом варианте изделия вытянутой формы из стеклообразного неориентированного или частично ориентированного полимера обрабатывают низкотемпературной плазмой. Затем нагревают до температуры выше температуры стеклования (Тс). Растягивают по крайней мере в одном направлении. Охлаждают до температуры ниже Тс полимера при фиксации размера изделия в направлении вытяжки. Во втором варианте неориентированное или частично ориентированное изделие из аморфного стеклообразного или полукристаллического полимера обрабатывают низкотемпературной плазмой. Растягивают при температуре ниже Тс для аморфного полимера и ниже темпер
